Using Slater's Rules: 3 Examples
HTML-код
- Опубликовано: 18 сен 2024
- Sorry this one's so long. But Slater's rules aren't the easiest things in the world.
Summary:
For an "s" or "p" electron:
Add up 0.35 for each electron in same group;
plus 0.85 for each electron in the shell below
plus 1.00 for each electron two or more shells lower
Then subtract this sum from the atomic number to get Z(eff)
For a "d" or "f" electron:
Add up 0.35 for each electron in the same group
plus 1.00 for every electron in any other lower group
Then subtract this sum from the atomic number to get Z(eff)

I love how you explained it in a clear and simple manner. Everyone over complicates it
I learned more in 11 minutes here than I have in all my lectures so far. Thank you so much!!!
Damn! You're good... You explained everything perfectly.
u are ryt
correct awesome explanation
Not understood when taught, not understood when read from book, but definitely know it now after watching this video! 6:47, who's awesome? You are! Great explanation.
You are very much better than my chem teacher . No one can understand when he teaches except him. But when i saw this ,wow it was damn clear . Thanks alot🙏🙏
Awesome Video...Didn't understand when I was taught..Neither did I get it when I read my book....:-o
But perfectly understood when I watched this vid..:-D Thanks a ton!! ;-)
Same here 😂😂
Me too
I still don’t get it lol
@@mastabeast1216 It's been 6 years since I made this comment.
Haha, now I don't even remember what Slater's rule was. :D
@@prashanthvaidya5220 so u must be working now right
wow!!! great explaination.
love from INDIA...
dude! you're the man!!!! I wish you were my professor! actually excited about what you teach THANKS!!!
nice! .. i wonder why my professor is making this topic complicated. thanks for the explanation
wow!!!! this man is too good. My teacher makes it very complicated. thanks a lottttt!!!
omg there are just few hours near me before my exam u just saved my semester thank you
I am a chemistry teacher student. The best explained
I've ever seen. Thank you so much :))
This video is well done; very organised presentation which simplifies the concept. Job well done!
You have explained slaters rule very well. I did not understand when i was taught in my college but now my concept is clear.
Thanks a LOOOOOT for your videos.
They are fun to watch and easy to grasp!
I thought about this concept for a while after watching the video and have come up with the below article...
please check this:
With regards to the first solution (as an example),
the effective nuclear charge as seen from a 3d electron is 6.25e,
Problem statement: To find what amount of charge on a 3d electron is seen by the nucleus after considering the fact that there is a large crowd of electrons in between...
Solution: We can say that as the nucleus exerts a pulling electric force of ke(6.25e)/r^2 on an electron, where, k = 1/(4 * pi * epsilon) and r is the centre to centre separation distance,
the electron must also exert the same magnitude of pulling force on the electron (Newton's third law and a concept from superposition principle - electrostatics)
so, if Q be the effective electron charge of a 3d electron as seen from the nucleus, then,
ke(6.25e)/r^2 = k(26e)Q/r^2 => Q = 6.25/26 * e = 0.24e (approx.)
then the effective electron charge of a 3d electron as seen from the nucleus is 0.24e and not e.
Is the above line of thinking true sir?
It looks like the article is applying the standard equation for an electric field to the effective charge. However, they are being sloppy with some of the terminology. Q, as they define it, is not properly called the effective electron charge. It is the effective charge of the nucleus acting on the electron. The equation they use would then give the electric force experienced by the electron relative to the nucleus (not the charge). However they give no citation for what value is used for r, which is very suspicious to me since this is the distance of the nucleus from the electron, and will vary based on the element and shell (and even then it would only be an average distance). So they do not even suceed in properly answerig the force experienced, which was not the original question of charge anyhow. Units are not at all taken care of here either. I would say this is a hack understanding of the concept and a hack understanding of how to use the math properly. This person failed their pchem class. haha
Didn't hear a thing, but understand it perfectly after watching the explanation with your hands 😂
I'm glad Chemist Nate is in our timeline.
"Bam!! Who's awesome? I AM!!" LOVE IT hahaha it has been very very helpful , thank you so much sir
Sir you are the most efficient teacher🔥🔥🔥
This video was made on a Request someone sent me years ago. Ask me anything !
@@chemistNATE how are you spending your quarantine
it's too good
my glance on chemistry has changed bcoz of u
keep doing this
thanks
you are awesome
I have also made it easy
I didn't get this before I got here and I've been searching the net for answers to no avail. You're the best!
Wow 10yr old video explained me well then all other channels failed to do that 😮😅 thx!!
Thnkuh so much... it really helps me a lot in clearing my doubts regarding Slater's rule..
Out of all the videos on youtube trying to teach this, this was the most effective one yet. But im sure you hear that a lot.
thank you so much, I couldn't find any French guy to explain this, you're my savior
I was very confused and tried many resources to understand the slaters rule and i was about to give up hope. This video was AWESOME! Thanks a lot from India
You just got me through a good chunk of my chem homework. Thanks a million!
i'm a junior in college and i've been trying to understand this since freshman year in high school. i just figured out how to do Zeff in 11 mins...thanks a lot, appreciate it
I do not have words to thank you . You explained it so well. Love from Pakistan
You da real MVP!!!
thanx alot. you save my life.
Ha ha, but how
so much easier to understand. slater's rules are very dense and this definitely helps to clarify them.
This is an amazing video that keeps helping people to this day, thank you
This is the most important Channel I have seen for chemistry students
only video available on RUclips on this topic that makes sense. thanks great job.
Thanks so much for posting this video! Went to lecture and this made zero sense, but when you explained it I got it right away!
I love the Practical Explanation, you're really invested Sir! Hat's Off...
i have never seen a clear explanation like you have done in this video, before by anyone else.
May I deduce that effective nuclear charge experienced by valence electrons determines the tendency of an atom to donate or attract electrons as it is for electronegativity?
Outsider!
very helpful lecture .... I have alot of fluctuations about this rule but when i watch this video my all problems were solved thank you so much.......
You literally explained better than my chemistry dr. Thank u so much!!!
I didn’t understand a thing at class!!!
you're better than my chemist teacher in VN,thanks so much
This is super helpful! I got so confused after reading the textbook, but the video is so great. I really like the different color markers.....
I love you're videos and hand gestures. Thank you.
thankyou sir.. it really helped.. till now i surfed many videos but none of them helped.. n you taught it in a very Simple way...thankyou SIR :)
This video was freakin awesome. I just learned this lesson today in my biochemistry class and I was so confused. You clarified so much. Dude, you are awesome. Definitely subscribing !
Thanks, you have made it much more cleare than my teacher. You're a life saver.
I didn't understand it before...Now I do.Great method of explanation👌
This video just clears it all thank you so much sir
I love the way you explained it's just very clear.
Finally someone who explained how to apply the "n" values
Thanks a lot for this great explaination because in next lecture our teacher have to teach this rule and I understand it now in advance 😁😁😁
That was so good. Seemed so easy!
Expressing gratitude from India :)
Nicely done, sir! I have an inorganic test coming up and this was a perfect explanation. Subscribed!
You rock it. I like! Thanks and it is so easy to understand compared to my teacher.
Thank you Sir!! I've actually understood slater's rule today God bless you .
Really awesome you explained like a pro. I didn't get it when I was taught in class
Thanks a lot ! It helped so much for a homework for inorganic chemistry in university... my teacher didnt explain this very well.
thank u sir !!!!! you explained concepts very clearly without complications
Thank u soo much...this video has helped me to understand slater's rule better!
u are so awesome so thankful for your ability to break this down to my understanding!!!!
This video is a blessing! It makes so much more sense now! Thank you for making this!!
Man that's such an amazing video! Cleared all of my doubts! Great Work, Keep it up!
Thank you so much, literally saved me for my midterm!
thank you very much sir.. actually I don't go to any tution. n tomorrow is my exam.. I wasn't understanding this concept by my book .. good explanation...
Aren't we supposed to deduct 0.85 instead of 0.35 ??
iamvarungupta the value of 0.35 is nd , nf ...... and 0.35 is use for ns np when last e- is filled in ns np. .... and 0.85 is use in n-1 shell if e- is filled in ns np
😅😅 I think
for d or f group...each electron in the same group contributes 0.35 for n shell .... for s or p ...each electron contributes in the same group 0.35 for n shell ...& contributes 0.85 for n-1 shell & any other lower group contributes
1.00
I'm taking the course for the second time, so thank you two times!
thanks You're Actually Saved me I'm having test tomorrow I completly Understand
very useful in solving,,,Thanks from Tanzania
Awesome teaching which helped me to score good marks
Bro u explained it perfectly
It helped me a lot thank you so so so much
god bless you bro
THANKS SIR...I have got a lots of benefits about Slater s rule..
My teacher sucks at teaching!!!
Thank you for actually teaching me something about chemistry.
You're a life saver! Thank you soo much!!
Great teaching..... It was awesome... Continue ur valuable work for other topics too
U explained so well ....
Thank u brother
Chai!Thank you, I really was lost in the lecture but now I get it.
You're awesome..!!! You are really a gr8 guy..!! success will keep following u
loved your video, it cleared all my doubts
Thanks buddy!! Your explanation really worked!
Hope you are well.
You explain very well. Thanks.
u r jus soo great !! ! :) !! it helped me a lot fr studying fr my exam !! :) !! thanku so much ..keep uploading videos of dis kind.. cuz it helps us a lot !! ;) !! thanx again!
You're so energic. Thx btw. I have to share n like this and all of your videos🔥
great video, thanks @chemNate!
wonderful explanation sir you just made it easy
Thnks.. wsnt able to understand when i read tht in my book .. Understood it bttr now
You're awesome man...The good thing for me is finally I've understood it perfectly but the bad thing is tomorrow is my exam :3 wish I had seen it before
Thanks a lot sir... This s so easy to understand
Job weldone.
U simplified the concept.
electrons in (n-1) contribute 0.85 of the tatal shield or screening.
This was a great video. Perfect explanation. Thanks!
Hey man, currently in office hours where the TA's don't even know Slater's rules. I know, crazy right? Well, here's my question: I am trying to figure out the Z effective for copper's 4s electron. I wrote the electron configuration as: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^1 (I went ahead and switched the 3d and 4s as you've instructed). My confusion stems from the 4s shell only having one electron. How can I take one less electron if there is only one? Is it 0 x .35? If this is the case then when I do the math I get 2.5. Mastering Chemistry is saying the answer is 3.7. Could you please clear this up for me? Thanks a lot!
This was a very simple explanation!! thank you very much!!.... you are amazing
Thanks a lot a lot for uploading such a useful video coz this video really helped me for understanding Slater's rule.
U r the best,now Imma go get my A+,thank you
4:14 ...it will be 8×0.35 because it's the same shell (n=3) as a 3d electron...from (n-1) we will start multiplying 1.....correct me if I'm wrong
Woaa man ... you rock !!!! Thanks for such an gr8 and clear explanation ...
Your video really helped me understand this! Thank you!
best teacher ever
