I’ve been asking this for years and spent a lot of time in the library and I can’t even find a record of some asking that question. It’s kept me up at night a few times. It seems that nobody knows why and it bothers me that it appears nobody is even trying to figure it out.
@@markb3786 Quantum stability and bond energy explain 90% of the differences observed. E.g. iodine has a weak covalent bond and melts (evaporates) at a low temperature. Silicon and carbon (diamond) have strong network covalent bonds and are hard and have high melting points. The noble gases are stable electron configurations and don't form bonds under normal conditions, hence are gases. Might be an idea to invest in a new chemistry book!
None of what you describe technically have to do with the title 😂 they all different trends with their own explanations, don’t confuse a short explanation of the periodic table with 3 years of high school chemistry 😂 I mean while you at it ask why he didn’t explain radioactive elements and beta alpha decay 😂 can’t cram everything in one spot, it’s inefficient
When I was a young chemistry student there was a simple rule to predict the tendency of an atom to acquire or give electrons : the rule of the "8 electrons outer shell ". Every element tends to complete this shell of 8 electrons: a) acquiring the missing electrons . b) giving the exceeding electrons. c) sharing electons with other atoms. Later I understood that at the basis for this there were reasons concerning energy and stabiity. However this rule works pretty well and I always wandered why it was sufficient considering just 8 electons instead of the entire electronic configuration.
I really hope that they're oblivious. "It has soy, you can drink it on lent." Then they're like "Why do people keep screaming at us that Soylent Green is people!?"
I love this question, but i love that a video on it was made. We need more videos with these types of questions answered. There are so many seemingly simple questions with profound answers that many of us wish were answered. Thank you!
Never understood chemistry so easily and smoothly in my whole life. If teachers like u r there earlier..... All the nations had so many chemistry lovers..... Can't even imagine. 👍👍❤
I don't think Oz would want him as soon as you looked past his phenomenal science contributions (although had he been living in the UK around 250 years ago you'd've gotten him by default and he'd've had to make his own hammock while he was building Sydney😉)
Fabulously explained, Arvin! I wish I had the understanding of QM and QFT that I have now back in high school, lol. This video also explains why I prefer to sit in the recliner watching QM videos than mowing 4 acres of yard...I'm in my ideal, low energy state!
Thank you so much for the video ash, I remember in high school and college the teachers would always list off or tell you the “what” and “how” for stem topics but when asked, frustratingly never would answer the _why_ things or processes exist the way they exist. And now onto the next video hopefully of you explaining the _why_ of the specific number for each electron shell, you explained the first orbital shell of 2 but none of the other ones.
Well explained. I've seen and read about the periodic table and sharing electrons but not the proton distinction before. This was pretty easy to follow and remember. Thanks.
I appreciate how you ask hypothetical questions that (is that the Socratic method ?) either match ones I have or have had, or…reinforce the concept by revealing a specific, and intelligent, question I should think to ask.
Let’s not get too picky here! The error is only approximately 1,6 x 10^7 m (or 10’000mi, in Imperial units). So not exactly Heisenberg’s uncertainty, but fairly within the range of measurement errors… But apart from this, Arvin, your videos are great. They help to make people think about physics. And “Physics is everything” (Don Lincoln, Fermilab).
I had no idea he was also Irish or a serial sexual abuser. Check out his Wikipedia entry. I only went to look up the Irish part. There's a lot about this guy no one discusses, much like his Australian roots
Hey Avi, just came here to thank you for your standard model video.. I just defended my thesis and now a PhD. Thank you for making it easy to understand, it was very helpful.
I found it to be a really funny homage. Like yeah absolutely it's meant to make you think of the old movie, but in a haha yeah mystery meal replacement way. It's not like the vegans have an evil secret cannibal cabal lol.
Chanced upon this video. I love how clear his explanations are, as he explored in depth, step by step, to address the subject matter. Love watching clean presentations like this. Subbed! Gonna binge watch more!
Hey Arvin, I wish you had also mentioned the “cloud model” of the atom in your video because this solar system model is now outdated and I would have loved to accurately imagine what the atoms look like and what electron position means from the cloud model perspective. Thanks for your amazing videos!
Like most educational videos, complex ideas start off simple for the beginner. There is nothing in this video for intermediate/advanced students, so the "planet/solar system" model is appropriate. Students need to visualize scientific concepts before they'll remember the basics. Then, you can throw the next level of detail at them.
You always teach Gen Chem students the bohr model first. It's the most basic way that still helps describe what's going on. It's best to learn it chronilogically just as scientists did. 13:51
@@samsonau8205 An educational concept known as "lie-to-children", as Cohen and Stewart put it and popularised together with Pratchett. The idea being: you teach the student something that's not, strictly speaking, correct. However, it gives the student enough understanding to think about it and eventually realise that it isn't correct. Then, when they start to ask the right questions, you can tell them... Well, another "lie"; a better one (a less wrong one), but one they can digest and really understand, not just memorize.
Models are never entirely accurate, but some models are better at getting certain concepts across than others. When talking about electrons and electron shells, I would argue that the solar system model is more preferred. Helps keep things simple.
Excellent video, as always. I hope to show these videos to my kids when they get older. You make physics and chemistry fun to learn about. There's a lot of young people in America who probably would know more about chemistry and physics from watching one or two of your videos than they would get from 12 years in the public school system.
As someone with little to no base knowledge of chemistry or physics, I really leaned a lot from this video. I remember in high school I would wonder about these advanced questions, but not be able to understand the answer upon researching, it’s very cool to revisit the same questions as an adult, and have everything make so much sense lol
There are a LOT of concepts of music, frequencies, balance and resonance that can be applied to the atoms properties. If you change a note by 1%.. it does not sound like the original song.. it sounds horrible. But if you change it by 0.5x or 2x it sounds perfect. The notes of music are like the energy levels of electrons where you cannot just go anywhere.. they must have harmony and resonance. If I am not mistaken... This same concept is where color comes from. Because the electrons wave must resonate(in a matter of speaking) with the rest of the electrons.. there are discrete energy levels or the atom will fly apart. When a photon hits an atom..the electron changes energy levelz and when the electron falls back down to the lower energy level, because the electrons levels are discrete... The wavelengths of photos emitted are consistent. This reminds me of pinch harmonics on a guitar. No matter where you create the harmonic it will always be in tune.. it will just have a different frequency still create a stable and harmonized tone that matches the music. It is because the atom or song requires balance of the frequencies that dictate that very minor changes can result in a massively different effect. you can easily change the frequency(number of electrons) greatly but retain a similar effect. This is why atoms with very different amounts of electrons(protons) can have similar properties(same columns of periodic table) while atoms with slightly different number of electrons(protons) have vastly different properties. Music and physics are my favorite.
What a nice video for us students that are starting with college chemistry and want to understand (and not memorise) all the stuff we learn. And btw, I do not want to be that guy, but wanna point out that at 7:57 it says that Schrödinger Australian-Irish was. If I’m not wrong, I think he was Austrian-Irish. Thanks for the video!
I mean, I also learned some more basic stuff related to chemistry in HS, but we never got in too deep with Binding Energy, Mass Defect, Strong/ Weak nuclear force, etc. it just was swept under the rug. In college we are being asked for sightly more complex stuff (1st semester), given that first they try to level all the student‘s knowledge so that they all can take lessons together, but still, a lot of topics more related to physics are being skipped because most people will not need that
@@TimTim-gm9pj in South Africa we learned the basics of chemistry from 8th grade so essentially all this video is saying. Then by 10th grade we learned them further as in the trends and how they work, intramolecular and intermolecular forces. All models of the atom from the raisin pudding to Heisenberg and by 12th grade we finished electro chemistry and organic chemistry and also a butt ton of stoichiometry 😭. In addition to physics cause it was the same subject and two 3 hr exams for finals but we had them every second term basically. The result was I practically learned nothing in Chem I when I got to college in the US and basically only in the end of Chem II did I learn some new stuff mostly just different types of orbitals and pi/sigma bonds which we did cover but not in detail in high school. All this to get to organic Chem I and the fun stopped after chapter 4 😭 my high school teacher did warn me ngl cause Ochem was easy in high school since we only had to do IUPAC naming both ways, as well as knowing all functional groups and if I remember correctly eesterificstion was the only mechanism we learned. Once I started learning proper mechanisms, sterioisomers, chiral centers and naming them properly that was the moment I sat in a lecture hall and wondered where I went wrong cause I was a marine bio major and had no need to learn organic chemistry in that much detail 😭 and that was Ochem I by the end of it I was like wtf more could there possibly be in Ochem II 😭 so to any chem majors out there who hurt you 😭 like talk to me
Thanks for that catch. The table is a stock image. We will refrain from using it in the future. Funny enough, nearly all stock images of the periodic table have errors for some reason.
@@ArvinAsh it's probably intentional errors to catch people using their stock imagery without permission. "you used a version with errors, and it's clearly ours!"
why is everything so limited in this universe and why does this universe exist in the first place. energy, matter, it all shouldn't exist. it would make more sense if nothing ever existed in the first place. did something else exist before this universe? are we in an endless loop of new universes coming to existence a very long time after the old one died? did we ask these questions already an infinite amount of times before? it all makes no sense to me. the energy, the limits, the fact that energy can create consciousness to be aware of itself. its just weird
Thank you so much, because I have been thinking of this same question for a long time. But now I understood clearly why the elements are so different. TH-cam channels like this help me to understand and study science better! 🙂👍
Not only that, but caesium is down as Sc instead of Cs, but it's also a few years out of date as all the elements from 110 to 118 now have actual names, not just the placeholder "Unun.." ones.
Agreed. Like of course it comes down to Valence Electrons, we all knew that already, and for that, the elements with similar amounts only behave "drastically different" from eachother, because you're comparing their reactions with different elements. Compare elements with just one proton difference to the same position on the table, the reaction isn't that special. The "complexity" is fully emergent
@@TrevoltIV I too wish we had a theory of everything but having simple non scalable models as to locally approximate reality in simpler ways is neat too
Great video Arvin! As a chemist (this don't affect the content of the video) I saw that an old periodic table was shown since we now have named atoms up to element 118 Og
@@jumbopopcorn8979 :- ) Never write pre-coffee jokes about science. Yes, Heisenberg. Uhm... Let's say that Herr Schrödinger was riding shotgun in that car. nice save from me L0L.
As a chemist, nothing here was really new to me, but it was still interesting to see it beeing explained by a physicist. Great video and explanation! :D
The thing that links this to chemistry is that if your molecule needs more elections in it's exchanging atoms then it's often on the acidic side, while the molecule that is needing to lend them instead tends to be more basic. Either of them tend to be more polarized than the molecules that have no ions.
This reminds me a lot of music: Two pitches that are almost the same, sound very dissonant and tense. While pitches far apart can sound very harmonious and similar.
This explains inter-reactivity from a chemical perspective, but does not explain how the proton/neutron counts determine other element molecular characteristics translating to how we see them (typically at room temp for example), ie, water is a clear liquid, iron is a shiny metal (vs it’s oxidized red form)
Excelent video. I just always just accepted it was the how atoms and molecules bond. But it always tripped me out with the exact example you gave. The fact that a gas goes to a metal with one proton is wild.
Dude thank you for always making such awesome science videos. You, Sabine and Matt at PBS Spacetime make the science trifecta! This topic in particular was always something I was curious about and you've explained it so clearly that now I can go teach my son and pretend that I knew it all along lol
I have to to partially disagree. Chemistry, Biology etc aren't just very complex physics. Theres also emergence, weak, strong and even radical. That doesn't mean of course that the smaller scale is completely irrelevant, but without any form of irreducable emergence (strong and beyond) nothing could exist. Since even the quantum decoherence process involves entirely new princimples and transition to a fundumentally differnt domain just with an interaction. If we take reductionalism way too seriously we only get "the thing", meaning space, time, gravity, every quantum field theory, are all the thing. And without new rules, the thing is not nearly enough to get an existence. The schrodinger equation only predicts the stability and validity of which atoms are going to be atoms and not isotopes, hence electron composition , atomic not molecular properties. And not to mention we already had macro knowledge so even if strong emergence is present somewhere it can be dismissed. For example, supercunductivity and bose einstein's condensate and more are irreducable and not understandable from bottom - up. So even with infinite computational capacity, No true turbulanse, tension etc would spontaneously born inside a deterministic computer simulation without additional parameters. Even gravity can be said to be reducable, to the emergence and interaction of the quark field (matter) with the higgs field. Alone they don't create space curviture, but we don't say gravity/mass are illusions and just the sum of the "deeper thing".
Ok. I understand all that. What still twists my brain around is how these changes manifest in such drastically different physical properties. At the beginning of each new energy shell is a reactive dense metal and at the end when that energy level is natively full, it’s a gas. In between, sometimes it’s a solid and sometimes a gas, sometimes incredibly hard or incredibly soft. Sometimes it’s a liquid. I know that changing the energy state by adding or removing thermal energy or mechanical energy in the form of pressure to the elements causes drastic changes to the physical properties as well. A lot of that has to do with the bonds settling into the lowest energy state possible for the conditions and I feel like I’m so close to understanding how, but I can’t find any resources that can answer the big why. The answer of “it just does” seems to be the prevailing one on this question and that has never been a satisfactory answer to me.
@@edus9636 I can’t even find any trail of people even asking the question. It gets stuck in my head sometimes at random and when it does it keeps me up at night.
A nitpick: At 10:02, you display a periodic table that's slightly out of date because it uses the temporary systematic names for elements 110 thru 118 (darmstadtium thru oganesson).
Thank you for educating us in such a profound way.....Lot of insightful facts made me curious and lot of my unanswered questions got their answers.....
Arvin, if you only knew how many minds you turn on with these. People you'll never meet. Who knows, perhaps the next Einstein ! You have this cool ability to present concepts that are completely graspable. Can't turn on a mind unless it can see ! Way cool, really dig these.
I have watched MANY of your videos with great interest but only limited intellectual competence; alas, too many are above my somewhat-dimwitted head. But not THIS one, Arvin! It is absolutely brilliant how you started with basic chemistry, and then quickly took it all the way down to the nonintuitive quantum realm. Geeze, if I would have had you as my chemistry teacher at my suburban St. Louis high school in 1971--instead of a genial, well-meaning redheaded guy who was profoundly LOUSY at answering my many hey-but-what-about? clarifying questions--I might be a six-figure earning chemist or physicist today...instead of a washed-up, ex-broadcaster. Keep 'em comin', please, Sir Ash!
Glad to know I remember correctly from high school Chemistry! Your Models at 12:00 are the best I've seen so far though! Those would be really nice to have in the classroom for understanding and making molecules, or even just for fun!

Silicon and carbon (diamond) have strong network covalent bonds and are hard and have high melting points. The noble gases are stable electron configurations and don't form bonds under normal conditions, hence are gases. Might be an idea to invest in a new chemistry book!
None of what you describe technically have to do with the title 😂 they all different trends with their own explanations, don’t confuse a short explanation of the periodic table with 3 years of high school chemistry 😂 I mean while you at it ask why he didn’t explain radioactive elements and beta alpha decay 😂 can’t cram everything in one spot, it’s inefficient
When I was a young chemistry student there was a simple rule to predict the tendency of an atom to acquire or give electrons : the rule of the "8 electrons outer shell ". Every element tends to complete this shell of 8 electrons: a) acquiring the missing electrons . b) giving the exceeding electrons. c) sharing electons with other atoms. Later I understood that at the basis for this there were reasons concerning energy and stabiity. However this rule works pretty well and I always wandered why it was sufficient considering just 8 electons instead of the entire electronic configuration.
isnt that a high school thing ?
@@zouinahadjsabri High school and 1° year of university

Kind of? 😅
note that orbitals form shells. the first shell has 2x e-, the next shell has 8x e-......then it goes something like 8, 18, 32....
That's called Octet configuration..

Fabulously explained, Arvin! I wish I had the understanding of QM and QFT that I have now back in high school, lol. This video also explains why I prefer to sit in the recliner watching QM videos than mowing 4 acres of yard...I'm in my ideal, low energy state!
Thank you so much for the video ash, I remember in high school and college the teachers would always list off or tell you the “what” and “how” for stem topics but when asked, frustratingly never would answer the _why_ things or processes exist the way they exist.
And now onto the next video hopefully of you explaining the _why_ of the specific number for each electron shell, you explained the first orbital shell of 2 but none of the other ones.
Well explained. I've seen and read about the periodic table and sharing electrons but not the proton distinction before. This was pretty easy to follow and remember. Thanks.
I appreciate how you ask hypothetical questions that (is that the Socratic method ?) either match ones I have or have had, or…reinforce the concept by revealing a specific, and intelligent, question I should think to ask.
Hi. Great episode.
One thing I spotted is that Erwin Schrodinger was not Australian, but Austrian.
Let’s not get too picky here! The error is only approximately 1,6 x 10^7 m (or 10’000mi, in Imperial units). So not exactly Heisenberg’s uncertainty, but fairly within the range of measurement errors…
But apart from this, Arvin, your videos are great. They help to make people think about physics. And “Physics is everything” (Don Lincoln, Fermilab).

Hey Arvin,
I wish you had also mentioned the “cloud model” of the atom in your video because this solar system model is now outdated and I would have loved to accurately imagine what the atoms look like and what electron position means from the cloud model perspective.
Thanks for your amazing videos!
Like most educational videos, complex ideas start off simple for the beginner. There is nothing in this video for intermediate/advanced students, so the "planet/solar system" model is appropriate. Students need to visualize scientific concepts before they'll remember the basics. Then, you can throw the next level of detail at them.
You always teach Gen Chem students the bohr model first. It's the most basic way that still helps describe what's going on. It's best to learn it chronilogically just as scientists did.
13:51
@@samsonau8205 An educational concept known as "lie-to-children", as Cohen and Stewart put it and popularised together with Pratchett. The idea being: you teach the student something that's not, strictly speaking, correct. However, it gives the student enough understanding to think about it and eventually realise that it isn't correct. Then, when they start to ask the right questions, you can tell them... Well, another "lie"; a better one (a less wrong one), but one they can digest and really understand, not just memorize.
Models are never entirely accurate, but some models are better at getting certain concepts across than others. When talking about electrons and electron shells, I would argue that the solar system model is more preferred. Helps keep things simple.

Excellent video, as always. I hope to show these videos to my kids when they get older. You make physics and chemistry fun to learn about. There's a lot of young people in America who probably would know more about chemistry and physics from watching one or two of your videos than they would get from 12 years in the public school system.
Arvin, you always ask the best questions! This one I never thought of and its so basic.

Oh, I've always wondered about this, thanks a lot for the explanation!
As someone with little to no base knowledge of chemistry or physics, I really leaned a lot from this video.
I remember in high school I would wonder about these advanced questions, but not be able to understand the answer upon researching, it’s very cool to revisit the same questions as an adult, and have everything make so much sense lol
There are a LOT of concepts of music, frequencies, balance and resonance that can be applied to the atoms properties. If you change a note by 1%.. it does not sound like the original song.. it sounds horrible. But if you change it by 0.5x or 2x it sounds perfect. The notes of music are like the energy levels of electrons where you cannot just go anywhere.. they must have harmony and resonance. If I am not mistaken... This same concept is where color comes from. Because the electrons wave must resonate(in a matter of speaking) with the rest of the electrons.. there are discrete energy levels or the atom will fly apart. When a photon hits an atom..the electron changes energy levelz and when the electron falls back down to the lower energy level, because the electrons levels are discrete... The wavelengths of photos emitted are consistent. This reminds me of pinch harmonics on a guitar. No matter where you create the harmonic it will always be in tune.. it will just have a different frequency still create a stable and harmonized tone that matches the music. It is because the atom or song requires balance of the frequencies that dictate that very minor changes can result in a massively different effect. you can easily change the frequency(number of electrons) greatly but retain a similar effect. This is why atoms with very different amounts of electrons(protons) can have similar properties(same columns of periodic table) while atoms with slightly different number of electrons(protons) have vastly different properties. Music and physics are my favorite.
What an elegant metaphor.
This reminds me of string theory. Lol.
Thank you for that comparison That's really cool The math doesn't lie lol
it's an awesome connection, you can tell why so many scientists like Einstein were hobby musicians!

Thanks for the video!
Allegedly he's from both until you take the measurement.
@Freddisred ROTFL...
Wait y’all learn this in college?? Wtf? I learned this in 9th grade or 8th bit of both
I mean, I also learned some more basic stuff related to chemistry in HS, but we never got in too deep with Binding Energy, Mass Defect, Strong/ Weak nuclear force, etc. it just was swept under the rug. In college we are being asked for sightly more complex stuff (1st semester), given that first they try to level all the student‘s knowledge so that they all can take lessons together, but still, a lot of topics more related to physics are being skipped because most people will not need that
@@TimTim-gm9pj in South Africa we learned the basics of chemistry from 8th grade so essentially all this video is saying. Then by 10th grade we learned them further as in the trends and how they work, intramolecular and intermolecular forces. All models of the atom from the raisin pudding to Heisenberg and by 12th grade we finished electro chemistry and organic chemistry and also a butt ton of stoichiometry 😭. In addition to physics cause it was the same subject and two 3 hr exams for finals but we had them every second term basically.
The result was I practically learned nothing in Chem I when I got to college in the US and basically only in the end of Chem II did I learn some new stuff mostly just different types of orbitals and pi/sigma bonds which we did cover but not in detail in high school. All this to get to organic Chem I and the fun stopped after chapter 4 😭 my high school teacher did warn me ngl cause Ochem was easy in high school since we only had to do IUPAC naming both ways, as well as knowing all functional groups and if I remember correctly eesterificstion was the only mechanism we learned.
Once I started learning proper mechanisms, sterioisomers, chiral centers and naming them properly that was the moment I sat in a lecture hall and wondered where I went wrong cause I was a marine bio major and had no need to learn organic chemistry in that much detail 😭 and that was Ochem I by the end of it I was like wtf more could there possibly be in Ochem II 😭 so to any chem majors out there who hurt you 😭 like talk to me

LOL this periodic table at 0:54 is just full of errors. Si for strontium under calcium??? Sc shows a second time but is now caesium😂
Thanks for that catch. The table is a stock image. We will refrain from using it in the future. Funny enough, nearly all stock images of the periodic table have errors for some reason.
At a quick guess, in an older stock image, you're probably looking at a "paper town" scenario. In a newer one, laziness or AI.
@@ArvinAsh it's probably intentional errors to catch people using their stock imagery without permission. "you used a version with errors, and it's clearly ours!"
Cesium doesn't look right either.
also 110-118 have names now, afaik.
Absolutely brilliant! Thanks for visualisation, superb!
why is everything so limited in this universe and why does this universe exist in the first place. energy, matter, it all shouldn't exist. it would make more sense if nothing ever existed in the first place. did something else exist before this universe? are we in an endless loop of new universes coming to existence a very long time after the old one died? did we ask these questions already an infinite amount of times before? it all makes no sense to me. the energy, the limits, the fact that energy can create consciousness to be aware of itself. its just weird
Thank you so much, because I have been thinking of this same question for a long time. But now I understood clearly why the elements are so different. TH-cam channels like this help me to understand and study science better! 🙂👍

At 0:28 what is silicon doing under calcium? Was this generated by ChatGPT? 😂
Lol what the heck
Omigosh, good catch. They also have *Sc* listed twice.
Not only that, but caesium is down as Sc instead of Cs, but it's also a few years out of date as all the elements from 110 to 118 now have actual names, not just the placeholder "Unun.." ones.

the best easy and also complex enought to graphically explain chemistry, thanks.
hell i like this dudes intro music
Absolutely, so retro.. feels like transported into early 90's..
That wasn't a very satisfying answer.
Agreed. Like of course it comes down to Valence Electrons, we all knew that already, and for that, the elements with similar amounts only behave "drastically different" from eachother, because you're comparing their reactions with different elements. Compare elements with just one proton difference to the same position on the table, the reaction isn't that special. The "complexity" is fully emergent
@@TrevoltIV I too wish we had a theory of everything but having simple non scalable models as to locally approximate reality in simpler ways is neat too

SOYLENT GREEN IS PEOPLE!!!!!
The thing that links this to chemistry is that if your molecule needs more elections in it's exchanging atoms then it's often on the acidic side, while the molecule that is needing to lend them instead tends to be more basic. Either of them tend to be more polarized than the molecules that have no ions.
Could you use the modern names of the elements? "Potassium" is actually Kalium, "Sodium" is actually Natrium etc.
What the fuck
It’s not just the number of the protons but the amount of electrons as well which makes the difference
Sure, but the amount of electrons is determined by the amount of protons

The best presentation on the functions and logic of atomic structure I've ever watched!
you're amazing. the way you deliver the knowledge we all know
As always a fabulous explanation for complicated things
The question posed in the title of this video immediately caught my attention. Fascinating subject.
This reminds me a lot of music: Two pitches that are almost the same, sound very dissonant and tense. While pitches far apart can sound very harmonious and similar.
Brings back memories of high school chemistry lessons
This explains inter-reactivity from a chemical perspective, but does not explain how the proton/neutron counts determine other element molecular characteristics translating to how we see them (typically at room temp for example), ie, water is a clear liquid, iron is a shiny metal (vs it’s oxidized red form)
Because there isn’t really an explanation 😂 it’s like asking why you are made of flesh and not wood or metal. The answer is because that’s how it is 😂
The few you can explain will also take a whole book shelf
Excelent video. I just always just accepted it was the how atoms and molecules bond. But it always tripped me out with the exact example you gave. The fact that a gas goes to a metal with one proton is wild.
Dude thank you for always making such awesome science videos. You, Sabine and Matt at PBS Spacetime make the science trifecta! This topic in particular was always something I was curious about and you've explained it so clearly that now I can go teach my son and pretend that I knew it all along lol

What's the problem with just learning about it?
@@wesleywashington1251 I didn’t say that I couldn’t but thanks for the helpful suggestion
I have to to partially disagree. Chemistry, Biology etc aren't just very complex physics. Theres also emergence, weak, strong and even radical. That doesn't mean of course that the smaller scale is completely irrelevant, but without any form of irreducable emergence (strong and beyond) nothing could exist. Since even the quantum decoherence process involves entirely new princimples and transition to a fundumentally differnt domain just with an interaction. If we take reductionalism way too seriously we only get "the thing", meaning space, time, gravity, every quantum field theory, are all the thing. And without new rules, the thing is not nearly enough to get an existence. The schrodinger equation only predicts the stability and validity of which atoms are going to be atoms and not isotopes, hence electron composition , atomic not molecular properties. And not to mention we already had macro knowledge so even if strong emergence is present somewhere it can be dismissed. For example, supercunductivity and bose einstein's condensate and more are irreducable and not understandable from bottom - up. So even with infinite computational capacity, No true turbulanse, tension etc would spontaneously born inside a deterministic computer simulation without additional parameters. Even gravity can be said to be reducable, to the emergence and interaction of the quark field (matter) with the higgs field. Alone they don't create space curviture, but we don't say gravity/mass are illusions and just the sum of the "deeper thing".

@@cosmosalbert5846 what??
Best and clearest explanation that helps bridge the physics-chemistry gap. Thank you so much!
Thank you, thank you, thank you Arvin! ❤ I've asked this question since highschool. Even throughout college, profs wouldn't give a straight answer.
I hear you. In high school, i always got circular answers too.
Ok. I understand all that. What still twists my brain around is how these changes manifest in such drastically different physical properties. At the beginning of each new energy shell is a reactive dense metal and at the end when that energy level is natively full, it’s a gas. In between, sometimes it’s a solid and sometimes a gas, sometimes incredibly hard or incredibly soft. Sometimes it’s a liquid.
I know that changing the energy state by adding or removing thermal energy or mechanical energy in the form of pressure to the elements causes drastic changes to the physical properties as well. A lot of that has to do with the bonds settling into the lowest energy state possible for the conditions and I feel like I’m so close to understanding how, but I can’t find any resources that can answer the big why. The answer of “it just does” seems to be the prevailing one on this question and that has never been a satisfactory answer to me.
In the beginning😂

I have watched MANY of your videos with great interest but only limited intellectual competence; alas, too many are above my somewhat-dimwitted head. But not THIS one, Arvin! It is absolutely brilliant how you started with basic chemistry, and then quickly took it all the way down to the nonintuitive quantum realm.
