WHY IS SODIUM A METAL BUT ARGON IS A GAS?
Electron configuration determines this. Sodium atoms can form metallic bond because the positively charge cation K+ forms an electrostatic attraction with the delocalized electrons from the outer shell. Argon cannot form such bonds because there is no delocalized electron nor cation formed, since the electron structure of the atom is already stable.

SUMMARY
Why does changing just one proton in the nucleus of an atom make a different element? How can a single proton make such a huge difference in an element’s properties?
The simple answer is: The number of protons determines the number of electrons the atom needs in order to be neutral. The number and configuration of the electrons of an atom determines its chemical properties. So since the number of electrons is determined by the number of protons, changing even just proton will change an element's chemical properties.
If so, why don’t we classify elements based on their number of electrons instead of protons? The reason is because electron numbers for most atoms, can be changed by taking on or giving away electrons to and from other atoms. This is the basis of chemistry. But the change in electrons does not affect the element's essential nature. It still retains its atomic properties.
But the number of protons never changes for most elements. It remains the same because protons cannot be exchanged with other atoms like electrons can in chemical reactions. So the proton count of an element does not change in chemical reactions. This proton number, in turn, determines the number of electrons the atom needs to be neutral. And that in turn, determines the behavior of the atom when it interacts with other atoms chemically, i.e., the bonds it can form. And this determines both its chemical and physical properties.
The proton number determines the propensity of that element to keep, give away, or share its outermost electrons with other atoms.
Electrons in the outermost shell of an atom determine its chemical properties. Why are there different electron shells? Atoms and molecules tend to favor the state with the lowest potential energy, because of the second law of thermodynamics - the law of entropy.
Solving the Schrodinger equation shows how the energies of the electrons in any given atom will be distributed in its ground state. When we solve it, we find that electrons are distributed in orbitals and shells around the nucleus.
An orbital can contain only a maximum two electrons due to the Pauli exclusion principle. The Schrodinger equation shows that as the number of electrons increases in an atom, they occupy different energy levels or shells around its nucleus. These shells can only accommodate a maximum of a fixed number of electrons. These numbers are 2, 10, 18, 36, 54, 86.
So for the few elements that have exactly these protons numbers, they will have the precise number of electrons that make their atomic structure energetically stable. Consequently, they will not have the propensity to take on or lose any of their electrons to other atoms. These are the Noble elements.
Chemistry works by elements trading electrons to form neutrally charged systems that are more energetically favorable, than the elements on their own. Proton number is key because it is the main factor in determining what number of electrons an element would prefer. It boils down to energy and charge conservation.
#protons
#elements
One could ask, why aren’t all elements noble elements. Why didn’t nature make all elements stable? The reason is that elements were formed in fusion reactions within the cores of stars or star processes. The fusion process results in nuclei with all kinds of different numbers of protons, not just the noble elements. Fusion is a nuclear process that just makes stable nucle, not a chemical process that optimizes electron shell stability. - วิทยาศาสตร์และเทคโนโลยี

I think what I like most about your channel is that you assume we know the basic concepts of what you’re talking about, so you only mention them to give context and then move on to the actual information. It’s so nice to hear from a science educator that knows the level of knowledge their audience has
Absolutely great video. At 64 years old this engineer never gets tired of learning new science.
Same here. Mechanical engineer in the process of retiring. I learned the fundamentals in chemistry in college, as we all did, but there were always some things I didn't quite grasp . This video helped clarify a few things. Very helpful.
I dunno, shouldn't everyone pretty much already learn this in high school or even middle school chemistry?
@@asdfasdfasdf1218 Not the quantum mechanics part, I don't think.

@@aMartianSpy Spoiler Alert !
Isn't that the movie about the uncle of our fearless leader?
Was wondering the same thing. Strange choice of name from this company.
Brilliantly explained. However, this only partially answers the question. The "why" goes much deeper for me, where lies the code that dictates the behavior of the element when changing its configuration? Why is it what it is? I guess we have to accept the old saying: because it is what it is. At least for now.
Let's suppose there is an island of stability for superheavy elements. Could we predict their behavior, or would we need to wait for nature to show us how they behave? We don't even know if this island exists, let alone make such predictions. To me, this just demonstrates how precarious our illusory knowledge of everything is.
Don't get me wrong, we have come a long way and made sensational discoveries, but our progress is small compared to the grand scheme of the universe. At least, that's how it seems to me, or maybe my "whys" aren't good questions. I hope I have been clear. Excellent content, as always.
Exactly and well noticed. Science has not an answer (yet) for the question why an element changes its behavior, else one could predict the behavior of ANY chemical reaction without having to resort to experiments. With such a knowledge one could predict and explain i.e. why mercury is fluid at room temperature even if this element would be still unknown.
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....

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.
Arvin, you always ask the best questions! This one I never thought of and its so basic.
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).
@@ralf-peterberg1083 When taking into account the entire scale of the universe, this error is practically nothing!
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
He's Australian now. Its on the Internet. And that's always reliable !
@@nickcunningham6344 yes you’re absolutely right!
OK, but you didn't explain what you said you would. You explained what causes them to react; that's highschool chemistry.
Why exactly is potassium a soft metal and argon a gas... Why do they have such drastically different forms? Is it's propensity to bond with itself in clumps? How? Crystals? Cohesion? Electromagnetism? Nuclear forces? Why the difference there. Why does light interact with one not the other?
Reactions due to valence shells is easy to understand and describe, mate...
Thank you! Thank you! Thank you! I like Arvin, but as a retired Chem E, this has puzzled me for years. Why are such similar elements from a configuration standpoint so different as I interact with them? What exactly makes this difference? This video was a good chemistry video but failed on the question asked.
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.
Exactly. Pretty clickbait video.
@@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
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.
Learning it with the Bohr model set my learning back a solid year. @@mcbaggins12

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!
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
the way you put it is just beautiful and simple. Thanks

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 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.

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
That’s because scientists simply don’t know why anything does anything. At the end of the day the universe is just designed to do things in a certain way

Great video, thanks
Brilliant video about the electrons
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.
A master's presentation! Thank you.
When, during novae and super novae, heavier atoms were formed they would be ranbdomly scattered across space. The question I have - and perhaps someone can provide an answer - HOW, why and in what phase of the process they clumped together to finally 'look like ores' that we find across earth.
I suppose this could have been during the accretion disk phase, but still remains the why and how? What mechanism?
I also have the same question
What i concluded is that, the particles in a protoplanetary gas disc need not be evenly distributed or homogenously mixed. Similar to how the salinity of various parts of Earth's ocean is different even after being a single water body.. so considering the huge size of the star, its possible to get kilometre sized clumps that form the mineral deposits on Earth or any other planet or moon or asteroid
I’m amazed at how much you packed into a short video
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! 🙂👍

Plz more on the schrödinger equation and why/how it predicts the number of electrons for the different shells. And maybe also something about how the equation predicts the shape of the orbitals 🙏
Thanks Sir 🙏
Great video! But I thought at the end you were going to explain why calcium isn't also reactive. I would expect that it would have the same reactive qualities of potassium but just not quite as much since there's two electrons on the outer shell instead of one.
Good suggestion. I will make a 2nd follow up video to this explaining why elements have the physical properties that they do. My videos tend to be information-dense, but in order to keep it around 10 minutes, I have to figure out what is the most relevant detail to cover. And this means not covering some other information that would also be interesting.
I never knew how much I didn’t know about chemistry. It’s so obvious and easy if you think about it but I just couldn’t think of it before. Thank you so much this video was really well explained and visualized.
I just have one more question. What about the elements above Fe which aren’t Noble Elements? How did they Form and why aren’t they all noble elements ?
I've been thinking about this for years. Thank you for addressing this topic. Too bad the alchemists never knew what really makes up everything.
Hi Alvin,
You say that only two electrons can occupy each electron shell but the diagrams show more than two electrons in the shells other than the inner. What am I not understanding?
