This chemistry tutorial covers how to calculate the average effective nuclear charge felt by an electron in any shell in at atom. www.thechemsolution.com
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.
@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!
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.
Absolutely. This tutorial was designed for students taking a basic chemistry class, but yes, there is definitely more to determining effective nuclear charge.

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.
@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.
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?
OMG I wish i had scrolled down because i was sitting here for like an hour trying to look up videos and in my text to figure out why the n=3 shell only holds 14 hhaaha :) thanks for clearing it up
As nice as this presentation is, there is more to determining effective nuclear charge than what is being presented. The value here is only a rough approximation. Another way to look at "shielding" is "repulsion", and different electrons "shield" to different extents. Even electrons in the same energy level repel the "target electron." For a more accurate value of Zeff, use the s, p, d and f sublevel notation and Slater's rules. There are many websites which explain Slater's rules.
seriously are you kidding me? If you're not, I'm so sorry for you... In for example the UK it's spelled coloUr, and before a vocal sound you can't put AN, just A. Now apply water to the burned area.

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

Loved the tutorial. I have watched others on the subject and this is the first one tha made me understand. Thank you
OHHHH, thanks:) In class we went over this in two minutes, so this detailed explanation was very beneficial.

SHE SOUNDS LIKE LUNA LOVEGOOD OMFG
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
its awesome people still post these videos for others
THANK YOUUU!
Thank you so much! This helped so much
this was awesome, thanks so much im not a chemistry person but this definetely helped me
this was so helpful and wow it was just added! just in time for my test :D
This video explained a lot to me. Thank you.
thank you for the video! the colors really helped.
Thanks for this awesome video! Very nice voice too :) Made this painful subject a little more bearable lol
But I thought the n=3 she'll can hold 18 electrons? Why are you saying that it can hold 14 only?
So helpful thank you!
Great video, thank you!:)
Does this also work for transition metals?
Awesome tutorial

it helps me a lot. wohaaaa. Thank you so much!!
your'e vidioes are the best!
you did an effective job at teaching ;)
i love the vids, i wonder if any of you now a similar channel for physics
Why don't v consider outer shell electrons while calculating effective nuclear charge for inner shell electrons
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?
Thank you very much. Clearer than the book I'm reading, that's for sure.
thank you that was so helpful
any good site giving detail information abt it please??
Great presentation.
do it with subshells
hi tnx for the respond , your video is really helpful , so i came back to watch it again
Tres bien. Merci!
thanks for your voice and your video
your lovely voice aww
thanks it was very nice explaination.
sooo helpful thank you ALLOT!!!!!!!
Good video, Thanks.
You have the MOST BEAUTIFUL VOICE I have ever heard!
thank you so much! my chem teacher never taught us this...
thank youuuuuuuuuuu you are amazinggggggggggg
;)
OMG I wish i had scrolled down because i was sitting here for like an hour trying to look up videos and in my text to figure out why the n=3 shell only holds 14 hhaaha :) thanks for clearing it up
omfg, thanks so much! The first tutorial to actually make sense to me . Have a quiz tomorrow . wish me luck :)
pretty sure she's wrong at 3:45 when she says n=3 shells can hold 14.... they can hold 18...

omg thank you!!!!!!!!!!!!!!!!! I will bow down before u
well i love ur voice =]
Blah, z* for a shell, I was looking for clarification for Z* of a particular electron in a particular element.
Do u have an app for this?
I favourited this video purely because of your voice ...
Hell ya! Nuclear charge!
THIS SAVED MY LIFE thank you :d
hottest voice i have ever heard in ages
Great voice.
LOL! I was just about to make the comment that she sounds like an American Luna!
Thank you . I love your voice
her voice is so convincing!!!
I like your voice.
I found a picture and she is so pretty.
you have a very cute voice
you sound like jasmine from aladdin :)
n=3 shell can hold 16 not 14
you sound beautiful
of course the comment with the most likes is totally nor chemistry related!!! :)
we get it....she made a mistake. Calm down. Shes only human....sheesh
wow, a black and white page of text is definitely going to make me remember this better! Thanks! (even my textbook has more colour than this...)
wow... I should post this on an EPIC FAIL site! just simply wow...
seriously are you kidding me? If you're not, I'm so sorry for you... In for example the UK it's spelled coloUr, and before a vocal sound you can't put AN, just A. Now apply water to the burned area.
remove the video or redo it or something, this is incorrect information and will only confuse people...
