idk man, this was taught to me at school, more in depth and showing how the orbitals "bend" in chemical bonds. You probably just weren't paying attention.
Your welcome! . Btw I got to this video from your previous one explaining Quantum numbers. I filled in some gaps in my chemistry today by watching your videos. Thank you very much and keep up the quality! I hope the rest of your week is awesome!
I know this is like... a really old video, but my Gen Chem class is flipped classroom (rip) and due to COVID-19 it's a lot worse. We're expected to do more work and your videos save me SO much time!!!! thanks a bunch!
Overall well done! but a few missteps: 1) the nucleus is not a node (which comes out of Schrodinger's equation). 2) the number of nodes is determined by n (principal quantum number), not l (azimuthal)-- you said the number of nodes increases as l increases, but it is n: For n=1 there are zero nodes, n=2 there is one node, n = 3 there are two nodes, and so on. 3) you stated that the shapes are important because of orbital overlap creating bonds. While this is valence bond theory, it is one of several models, none of which can claim to be definitive, and valence bond theory is a fairly limited model. Otherwise you have a lot of good information here. Thanks for your effort and the stimulants.
Kind of an aside for those interested, but there are very special instances within nuclear physics and nuclear chemistry in which an electron can be located within the nucleus; specifically, during a brief moment just prior to electron absorbtion (a form of beta decay) and during certain states of nuclear excitation of the strong force. The first case happens when an unstable isotope of a heavy element allows a proton to snatch an electron from a lower orbital, transmuting one of its up quarks (charge of +2/3) into a down quark (charge of -1/3), as well as a neutrino (basically an electron with no charge and almost no mass, which makes even highly energetic neutrinos extremely difficult to detect). Also, this form of beta decay often leaves the nucleus in an excited state, as the positive charge pushing against the strong nuclear force (the one that holds the nucleus together). The excited state of a nucleus is very similar to the excited states normally associated with electrons, electron orbitals, and photon emissions of chemicals; except, the nuclear excitation is held against a much stronger (pun intended) strong nuclear force which will, eventually, return to the most energetically favorable ground state, emitting a gamma photon (think uber high energy photon), an electron which sits inside the nucleus, or even a further decay via an alpha particle (a streaking naked helium nuclei) and another beta decay (transmutation of a neutron into a proton or of a proton into a neutron). All of this being said, generally the latter instance of an electron inside the nucleus occurs only in meta stable fission products (which will undergo further decay) and the time the electron can spend in the nucleus is not well established (it maybe ejected as part of beta decay or be boosted out with a future nuclear excitation giving it sufficient kinetic energy to overcome the charge forces binding the electron to the positive nucleus). Of course, for the vast majority of chemical interactions and in the case of almost all of chemistry, this knowledge is useless and does nothing to advance ones understanding of orbitals (the subject of the video).
Exactly - as in K-electron capture. Fe-55 is a well-known radioactive isotope that emits the Mn K-alpha & K-beta X-rays by K-electron capture. We used them all the time to calibrate the ADC in X-ray spectrometers with Si(Li) detectors. I always suspected that this could occur because the spherical shape of the s-orbital might allow the electron to pass through the nucleus.
"Neither the beta particle nor its associated (anti-)neutrino exist within the nucleus prior to beta decay, but are created in the decay process." -"Beta decay" Wikipedia article
@@BensChemVideos Feynman diagrams are also defined as the average of all possible interactions between two particles. I haven’t seen anything preventing the possibility that electrons exist within a nucleus, especially since a nucleon is considered the left over sum of all virtual particle interactions within the nucleon. There are a lot of conflicting understandings in our current frameworks. I like to keep an open mind.
@@BensChemVideos All that said, I appreciate you living my dream from 20 years ago. Sometimes life has other plans for you when you dream of being a theoretical physicist. Thanks for allowing me to live that dream vicariously through you.
For the non-spherical orbitals, aren't the electrons revolving around the nucleus. How to comprehend non-spherical shapes when we are told electrons go around the nucleus !!
thanks for being my REAL chemistry teacher
Really

I wonder why the teachers at school are unable to do this in 40-45 minutes, which the youtubers do in only a single short video.
Bcoz some guys r not there to study and they disturb the whole class
Some of them are able, I had one in 1975.
idk man, this was taught to me at school, more in depth and showing how the orbitals "bend" in chemical bonds.

Sweet piece of work. Love it. Especially the f orbital visualization, I've not seen that version before and it really helps nail it down
Hard work, caffeine and perfectionism. Haha, I can relate. You've earned yourself a new sub. Thanks for the informative video, much appreciated bud.
Awesome Video!
existence of some people like mr.ben is just a Great fortune , thank you 👏💗
This video is a gem! Thank you
You're very welcome! Thank you for your kind words, and thanks for watching!
@@BensChemVideos 😀
This makes a lot more sense than my chemistry professor, thanks!
That's the goal!
Thanks so much for watching 😀
Thank you 😀😀
You're welcome 😊. Thanks for watching!
Lol the humor combines with the chemistry and creates an awesome video!

Could you perhaps suggest any resources that might lend themselves to predicting bond formation? I'm unsure of the limitations of valence bond theory.
Im from Brazil and i found your videos better than we got here. thanks for sharing your knowledge.
Just discovered your videos today and I have to say thank you so much!! I have exams next week and you have really helped me understand MO theory!
Thank you, SOOOOOO helpful!
You're super welcome! Many thanks for watching and commenting 😀
this vedio was soooo GOOOD!! KEEP IT UP
You are a lifesaver, keep them coming!
This video is brought to you by Hard work, Caffeine and sheer perfectionism // :)))))
I loved the ending lol XD
Thanks for talking about the shape of an atom. I was not sure that orbitals were superimposed until then.
You're very welcome! Many thanks for watching and commenting 😀
nice video, thanks so much
Great video! As much as i hate chemistry i was able to sit for the whole 7 minutes :)
Thanks so much! 😀
Great work man!
Thanks a million Ben
You're very welcome! Many thanks for watching 😀

Mr chemospider man....lol
Ben's Chem Videos Thank you for the videos, they are awesome!
Without this video I would never understand that.
Great job, Ben! Great delivery. Thx.
Thank you ❤️
You're very welcome! Thanks for watching!
thank u so much sir.... i could clearly understand the concept of nodes.... thanks to u....
This is an amazing video! I wasn't looking for anything this in depth but I am not dissatisfied!
This dude talks exactly like Sheldon!
Bazinga.
Doubts perfectly cleared! !😌
Awesome! Glad it helped! Thanks for watching! 😀
Very well defined explanation ....
Thnx... It helped a lot... But still expected more information....
Thanks from Ethiopia

Watching this video from my sister's phone. I'm now gonna subscribe to your channel🤑. Thanks for helping 🙏
Good one! At last I have an inkling of the shape of the f-orbitals, which others seem to avoid.
Good work my teacher and thanks🤗
Fantastic 👆👆👆🙏🙏🙏
extremely fascinating and helpful thanks
Great job guy
Thankyou very much! Your videos have been very helpful to me!
thanks, good video for understanding how orbitals work. We just got introduced to them today in Chem 11.
Badhiya
Great video.
Can you share link of your vedio about orbital and quantum numbers please

Superb

Great video sir!
Thanks! Makes much more sense than my first year chem course in university @__@

hi ben exallent videos keep goingon
Nice one :)
how are these shapes found though?
