Chemistry is the study of matter and energy at the scale of atoms and molecules. As the most all-embracing discipline there is, it should be at the top of everyone’s list of must-learn subjects. Unfortunately, chemistry has an undeserved reputation for difficulty and abstraction. Any subject that encompasses as many components as chemistry is going to appear complex. The beauty of delving into the study of chemistry is the discovery of how organized, logical, consistent, and powerfully predictive it becomes-if properly presented.

I am a 70 year old beginner. This video was very helpful and made the idea of studying chemistry far less scary!
Love the "no nonsense" style of presentation. Quiet, calm, lucid not cluttered the the mess created by media students.
Outstanding video: well explained, interesting, informative and superbly narrated.
You ever wonder why kids are confused by chemistry? Well, here’s a perfect example - a cation is a POSITIVELY charged ion, and an anion is a NEGATIVELY charged ion. Simple enough, right? But then you have a cathode, a word that also starts with “c” (you can even go as far as “cat”...3 letters...similar to “cation”), which is a NEGATIVELY charged electrode, and an anode, which is a POSITIVELY charged electrode. Wouldn’t you think it would be easier to group the similar names together (regarding charge)? Cation...cathode = positive; and anion...anode = negative (or the other way around). What genius thought opposing the names of charges would be better?
You are correct in that the words cation and cathode as well as anion and anode have the same root. The reason is that in electrochemistry once you put two electrodes in liquid and switch on an electrical field (so you have a cathode and an anode) the ions in the liquid will start to move according to coulomb's law (ie opposite charges attract each other). So how to distinguish the different sorts of ions in the liquid? Well, scientists said, let's call the ones that move to the cathode (the negative electrode) cations and the ones that move to the anode anions. So there is an underlying reason for the nomenclature with built-in mnemonics. You just have to wrap your head around it ;)
Amen!
@@MrKStoertebeker I just had to hear THAT! Now I get it. This has been bugging me since I started this autodidactic pedagogy thing years ago.
Thanks for pointing that out!
Well now I can remember cathod anion same!
@@MrKStoertebeker hey I’m going to Ignasious School and Adelphos no no I don’t see him. I saw him pass to make a phone call with Junius that is not.
Nice one!
It's possibly worth mentioning that anions are so called because they collect at an electrical anode; and vice versa for cations. Otherwise it's a bit confusing that cathodes are negatively charged, but cations are positively charged.
Also, some chemists and many biochemists refer to an atomic mass unit as a Dalton.
I stumbled on this channel today and I decided to check out this video. Damn! you did a-lot of work to put all these together just for our understanding. I really appreciate you, and I plan to be more frequent on this channel so as to learn more from you. Kindly treat other topics on this channel.
One year of not understanding chemistry in school fixed in just 30mins ❤️❤️
Thank you for this. Years of college, minutes on youTube. This is great. Thank you. Opportunity for more Great Minds to manifest from watching your intellectual videos.
I'm currently in the middle of the course. I took General Chemistry over twenty years ago at WVU and the professor I had was my all-time favorite. Dr. Davis reminds me a lot of him. Excellent class!
So easily explained with scientists' names and I liked the conclusion with the repetition of the material. Very professionally made, thanks a lot👍
Outstanding video: from basic to complex, explained in a way that anybody can understand!!!!
Excellent coverage for one and all of us to understand the basics of all the matter of the universe Thanks a lot
Wow, I love this, will share with my grandson. It is explained so clearly.
Thank you for this excellent presentation.
Wow! Amazing explanation with examples at every point. Thanks!
My son would love this .. good stuff!
more please yom yom yom :)
fantastic series. ty
Another fascinating fact about electrons : Each one is different according to Pauli principle, like individuals.
Great lecture, very lucid and clear. Thank you.
THANK YOU...
DR. DAVIS...!!!
Very useful video....tnx
Nice video, thanks for reintroducing the accurate model of the atom, I think kids are confused today because science keeps trying to draw it using the more schrodingerian philosophy of, because I don’t know where the electron is….. I’ll draw one in every place it might be.
Great explanation!
Wow very good video thank you.
Just brilliant!!!
beautifully explained
the best video class i already watching cogratulations
Thanks for the feedback, Elson! It is much appreciated. Never stop learning!
Excellent lecture. Thank you very much 🙏🏻🙏🏻
Good work! 👍👏👏
One thing for sure of the electrons orbits around the positioned protons, is they share the same rate of gravity for holding unity.
Sir can you please make a video on how Avogadro's number was first calculated?
There are two fundamental flaws in our concept of ATOM:
1) The term is not identical with what Democrit called so. We simply misconceived (rather, misnamed) something divisible as ATOM and now boast we have split the atom. There can't be an absurder SCIENTIFIC claim than this, as Democit's definition of an atom would simply shift to the smallest ever particle (electron, hadron, photon, boson or whatever else) one can split any substance into, and still remain indivisible .
2) Our "clever" way of naming existence of charges, spins, forces, energy (and now even DM and DE) when the formulae fail to account for observable phenomena, simply show that we failed to explain phenomena as results of particle interactions only. Period.
This method of inventing new names, when one name fails to explain events consistently, is the good old trick religions used very successfully by inventing devil, demons, fairies and evil ghosts when an omnipotent and omnibenovolent GOD failed to explain evil (confirmed by the fact that the vast majority on this earth still swallow it) .
Only way to avoid creating all these "word jungles" is to realize that particles possess MOBILITY in different directions, link them theoretically to digits, then to the 4 basic arithmetic operations and finally to growth of plants with a mathematical model of the mechanism how particle interactions inside the earth compose seeds,water and fertilizers that enable their growth, instead of explaining why apples fall and what uncontrollable by us forces move celestial bodies, which "explanations" don't serve to practically satisfy needs of beings as such a description would..
With that doscovery the concepts of forces, energy, charges, spins, etc.would all become superfluous as MOBILITIES of different particles, with different magnitudes and directions, would remain the single property of matter necessary not just to explain, but to practically satisfy needs of all beings, the only criterion of proof for useful knowledge.
Excellent🙏
Simply fascinating!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you for this info. 👏👏👏
Nice video. Thanks 🙏.
great! thank you so much!
Is it commonplace in chemistry to use 'react' as a transitive verb? There’s certainly a need for such a word but I’ve never heard it before.
Please continue the good work....
Nicely explained
Great stuff!
What an awesome piece. So we’ll laid out.
Great explanation of atoms for beginners and others. I want to enjoy more! Thank you.
Great video!
Excellent!!!
Thank you sir for being so. rational. And systematic
Very well done
Why electron doesn't fall in the nucleus, nucleus has protons positively charged and electrons are negatively charged so as per electrostatic force electrons and protons should attract each other but they aren't. Why?
This is very good. 0:02
Excellent
Very exciting
Excellent!
Atom has always had a mechanic of change according to a due set time...
11:00 i seen this experiment . well a version for string theory
So when they go to college understand what's going on what about all those kids that are going to be confused of this. Are they taught this in public Schools . When they go to college they will not be completely confused.😢 That would be a good idea.
The wrong music video I don't see anything wrong with it. Taught at the lower level so kids going to college can have a basic knowledge of what you are actually talking about. A basic 101 level would help.
Would carbon 14 be an ion considering it was a nitrogen atom which has more electrons? If all that happens is a positively charged proton decays into a neutrally charged neutron, it now seems like it would have a net negative charge.
very good
Subatomic particles (electron, proton & neutron) and space within atoms are made of submicroscopic quantum particles.
perfect description for a 2 year old: the universe is fundamentally a singular, extra dimensional, paradoxically self differentiating object. everything, at all scales, can be derived from this fundamental characteristic. self similarity, information communicability, even perceptual experience and representative abstraction. standard model "objects" are knot bundle configurations of the reality object substrate. the higher dimensional config explain all seemingly paradoxical activity such as non-localilty & translocation. a perspective's arbitrary differentiating exclusion/selection process is what gives objects the appearance & presentation of separateness as a natural result. chemistry studies the characteristics of changes in the corresponding geometries of these knot configurations. any questions? ok, now each your broccoli Timmy or you're not getting any ice cream.
Awesome
I think get messed up chemical, electric, mathematics,physic definitions. In chemical as far I remember only know atom word, example atom H (hidrogen),Atom O(oxygen), etc.
9:52 I saw something similar to that on a Egyptian wall
only five thousand see this video, amazing
What if he was talking about quarks referring to atoms then later scientists misunderstood him and misrepresented his theory by later naming alluding to a quark as an atom and allocating the name atom wrongly?
I Wondered that How peoples at that were able to Archive that level of vacuum in mordern days we have rotary vacuum pump to Get 100 to 10 micron of Vacuum but even This is not Enough you need to attach Turbo and Defusion pump also with also lots of other teckniques like Glass to metals bonding , Induction Glittering , outgassing Knowledge of Different Different Materials so on !! Than how ??

I wonder why protons never gets attracted towards protons and why is it mixed with Neutron?
Edison discovered the electron, when he inserted a second plate in an electric bulb.
This is the Edison effect.
Atomic structure theory
Atroms are eternal electricity generators and transformers.
All atoms consist of indestructible, electrically charged hollow sphere and internally charged solid sphere. What are called electrons are actually negatively charged liquid attached to the surface of the atom.
The hollow sphere has multiple layers, each with an opposite charge.
The inner sphere and inner layer of all atoms have the same charge.
According to Coulomb's law, the inner sphere of all atoms are oscillating constantly at a natural frequency and never can touch the inner layer. Theoretically, the ability of an atom to carry any amount of energy depends on the input.
Due to every atom has equal positive and negative charge. Therefore they all attract each other like magnets attract magnets no matter direction or distance. This is the mechanism of gravity.

Hey! I recognize that guy!
The basic structure if the atom is completely unknown. We've taken knowledge of the manifestation of something that cannot be seen and only indirectly detected and named individual aspects of the manifestations, mostly in a broadly guesswork manner, using language that is completely inadequate for that purpose, then some think they know enough about these things to go pontificating as if they are some kind of expert.
Simple...
atom as word comes from ancient Egypt
Do you think all black holes are made up of particles as well? Do you think parallel universe exists becuz of black holes?
Odd how every atom balances its self in exactly the same way. In humans we have instructions coded in DNA that gives structure.. what information is being transferred to balance the atom, where/what is this information. Or is it simply a curve, x amount of protrons and neutrons creates y curve attracting z number of electrons. Weird
99 protin and 100 nutrion what that made
👌👌 🇧🇩
Catchy intro tune
I wonder what that is - sounds like U2 or maybe Coldplay
The division of the atom stops the function of the atom.
OK so this is Lecture 5? 5 of what? Where are the rest? They're not labeled, it's just a catalogue of stuff.
This is lecture 5 of the "Chemistry and Our Universe: How it All Works" course.

Very vlesr
I almost feel bad for the scientists searching for the “most fundamental particle,” like they never seen a mandelbrot set.
I SUGGEST THIS IS THE BEST YOU'LL FIND ON U-TUBE,,,, ATOM IS THE SUM OF IT'S PARTS
>>>>>>>>> ""PARTS"
based the word "atom" on the Egyptian god Atum, the one who called for the first land mound from the watery void or vacuum.
“ in all of creation?” Serious?!?
I invite you to see ( 2020 Hydrogen atomic model ). Electrons Doesn`t ORBIT around the atomic nucleus, they oscillate or vibrate.
#wondrium I am from India and huge fan of you I have subscribed, share and comment your channel but you probably don't like Indian because you neither like comment nor highlight.Should I unsubscribe your channel and stop watching, commenting and sharing?If I don't get any response from your side then what other option is there to stop seeing you?
Another great example of how "science" has no real grasp on the foundations and just keeps guessing but yet always demands they are still correct. It would be more honest to just say they really still don't know. At that point we can spend more time analyzing the foundations with new thought because obviously this is still incorrect. "Probability clouds" enough said.
Another great example of someone using "science" to decry science 😅
What if..
Light is a wave, you know these orbs we see flying around.. Maybe the are atoms split looking for there other half in another dimension until they find it and bang thunder and lightning.
How do scientists know the atomic structure of an element when it cannot be seen physically. Has protons and neutrons and electrons been seen under a microscope? the answer is No. They can barly see an atom, let alone an atoms DNA structure. so how do they know what each element contains in its atomic structure.
Two ions are walking down the street. One ion says to the other ion "are we going the right way?" The other ion replies "I'm positive".
Looks like planets in a solar system
Ever consider that there is nothing "atomic" rather that there is infinite complexity? Everywhere
Why we still can't cure cancer Atom 😊
👍👏👍👏👍
Um, not sure that this helps students at the end of the day. The depiction is of course very basic and may confuse students later in their studies.
Way to smuggle in some religious baggage! "One of the smallest systems in all of creation...".
Yes, you set it up a few sentences earlier by remarking how nature creates larger structures from smaller ones, but then jumping to "creation" is awkward to the point of deliberateness.
"Creation" - you're gonna have to prove that.
