Effective Nuclear Charge - Chemistry Tutorial

This chemistry tutorial covers how to calculate the average effective nuclear charge felt by an electron in any shell in at atom.

yes, sorry about that, I misspoke. It should be 18. This was addressed in earlier comments but they are rather far down the page now. In the process of editing the video.

i like her voice, somehow makes it easier to pay attention to / interesting

[TheChemistrySolution]

yes, I made a mistake. I mentioned this in an earlier comment but it is rather far down the page now. the n = 3 shell can hold 18 ELECTRONS. sorry for the slip up. I will edit the video asap.

its awesome people still post these videos for others
THANK YOUUU!

[jasleensingh]

Thank you so much...this helped a lot! You put it in simple terms which made it really easy to understand! Thanks again!

n=3 can hold 18 coz 3s3p can carry 8 and 3d carry 10

[TheChemistrySolution]

@pacslife20 you are totally right. the n =3 shell can hold 18 total electrons. sorry for the slip up, didn't mean to say that wrong. thanks for catching this!

[JaxAkaJT]

But I thought the n=3 she'll can hold 18 electrons? Why are you saying that it can hold 14 only?

[TheChemistrySolution]

Absolutely. This tutorial was designed for students taking a basic chemistry class, but yes, there is definitely more to determining effective nuclear charge.

[vicaylor]

this was awesome, thanks so much im not a chemistry person but this definetely helped me

[pacslife]

pretty sure she's wrong at 3:45 when she says n=3 shells can hold 14.... they can hold 18...

OHHHH, thanks:) In class we went over this in two minutes, so this detailed explanation was very beneficial.

@1slvrfisher As I responded before, this video isn't meant to be a complete, comprehensive overview to effective nuclear charge. this video was designed to cover a simple method for estimating effective nuclear charge for those taking a high school or first level college chemistry class and is the way this is explained in most general chemistry textbooks. If you are looking for a more detailed explanation than this video is not for you.

[RiotFinger]

This video explained a lot to me. Thank you.

[yardyknowtho]

you did an effective job at teaching ;)

[nanoveneer]

hi tnx for the respond, your video is really helpful, so i came back to watch it again

[AlexDC]

This tutorial was great but I was just wondering why in the chlorine example the outer shell had no effect on the shell of interest as I thought that the outer electrons would push the inner electrons towards the nucleus which would be like like shielding in reverse as the electrons would be pushing in the other direction. I guess this is not the case due to the shape of the orbitals not actually being circular for most of the electrons but any help would be appreciated.

Very helpful video. One question though, what unit is the answer supposed to be in? Not even my textbook gives a unit, but surely it is not a dimensionless number?

Thanks for this awesome video! Very nice voice too :) Made this painful subject a little more bearable lol
