I've been watching all your videos on 1.25X speed to cover more info in a shorter amount of time and it's so much more intense. And great explanations, thank you sir :') lifesaver seriously
Please suppose that two electrons are moving in a single orbit, and suppose that the de Broglie wave of one electron shifts +λ/2 in coordinate and the de Broglie wave of another electron shifts -λ/2 in coordinate. The two waves have the shift of exactly one wavelength, which leads to a constructive interference of the wave, making it possible for the two particles to move in the same orbit. [the 4th quantum number] I'm sorry that I'm not good at English.
I may make a mistake, but L is not the number of subshells. Rather, L=(0,...,(n-1)). So n=3 has L=0,1,2 which is 3 subshells. Am I right because it says otherwise in this video? Or maybe L=n-1 is the highest subshell?
6:10 The reasoning you give for why the sub-orbitals must be perpendicular is a non sequitur. Whether or not your spatial coordinate system is orthogonal, the sub-orbitals will still be. I'm not an expert (yet), but I suspect this mistake/oversimplification is rooted in the assumption that the sub-orbitals are axis-aligned at all. Rather, I suspect that the fact of the orthogonality _of the sub-orbitals_ is what *allows* them to be drawn in an axis-aligned way.. but the choice to align them to your coordinate axes is totally arbitrary. If I were you, instead of calling the sub-orbitals p_x, p_y and p_z, I would call them p_a, p_b and p_c, noting that there exists some (unspecified) 3D rotation which will align them with x, y and z. Yes I know this video is a decade old.
Dear sir, first of all a big thumbs up ...... But one clarification sir you mentioned Px as -1 Py as 0 and Pz as +1.. but what i have understood is that Magnetic quantum number gives the z component of the orbitals and so Pz is the inter nuclear axis it should be taken as 0. Moreover we cannot precisely say Px as -1 it could be even +1 ..... Please clarify...
RootDubz93 Actually it isnt exactly 90% :-P it was used merely as an example to demonstrate that wave functions (orbitals) are given in terms of probability values. sorry if that was a confusing point.

Watched 10 videos still not understood.. But this made me clear
Thank s
folks, take notes! this is amazing! thank you soo much! well explained
It's awesome it's really very interesting when you teach sir
I really like your explanation in the video. Alot clearer too. Thank you very much for putting the effort to helping us understand.
:) Thanks! Im glad to hear that.
the explanation is superb. Thank you.
you are so thorough! thank you
you are .................. perfect in transforming and explaining
Thank you Hassan!
You are so good at explaining :)
Thank you sir. Now I don't need to touch my book at all!
that was so helpful, thanks:)
sienna richards you're welcome :)
thanks so much. Very helpful and easy to memorize.
your videos are helpful! I really thank you so much!!! 😊
Thanks alot, very helpful.
Big thanks

Awesome!

Yeah that's right.
Actually,
n = no of orbitals = no of subshells.

Tnks sir it was helpful
thanks a lot.............................
很详细，

thank you sir by vivek
Thank you! This was such a great refresher :) u
You're welcome! :)
wow i understood that. it made no sense in my class. thanks
Why is there specifically a 90% chance of finding the electron within the shape of the sub-shell? Why not 95?
RootDubz93 Actually it isnt exactly 90% :-P it was used merely as an example to demonstrate that wave functions (orbitals) are given in terms of probability values. sorry if that was a confusing point.
This was really clear I understand much better thanks a lot just subscribed BTW way all the way in jamaica in the Caribbean this is helpful👍👍👍👌👌.
6mtt thats great! thanks for subbing ! :-) awesome to see viewers all the way form Jamaica!
Your welcome 👍
What is and so on? I mean you have 7 principal quantum numbers and four subsidiary, how?
Can anyone answer this
How many electrons are there for an element whose last electron has the following quantum number n=5, l=4, m=-2, s=-1/2?
