12:44 Mam we should remove electrons from 4s orbital not from 3d orbital 👍
Yes
Yaa
Then it will become 0?
@@studyboyy in 4s zero but not in 3d and n=2 is crt
In next problem
4s become 0
3d become 6
And then n=4 right
log antilog video pls🙌🏻🙌🏻🙌🏻

Dear mam
n = Atomic number of given element - oxidation state - At . number of argon(18)
# If n = 1 to 5 , all are unpaired electrons.
# If n > 5 , then number of unpaired electrons =10 - n.
All the best my friends 👍🤝
3:35mins (8 multiplied 4)is 32
Mam the electrons are lost from outer most shell i.e., from 4s
E C of Ni+2 :- 1s^2 2s^2 2p^6 3s^2 3d^8 4s^0
Wrong
13:30 We first have to remove electrons from 4s orbital and then move to 3d orbital. So 2 electrons are removed from 4s orbital in Ni²+ and 3d⁸ will remain as it is. When it is filled in the orbital 2 unpaired electrons are obtained. Hence n=2.

@@Punith2k5 Sorry, my bad. I corrected it now. Thank you for informing.
vote for mcq's plzz👇👇
29:23 mam first we have to remove electrons from 4s then 3d
Who want partB imp fixed questiiionss 😊
I want it
I want 😂
28:37 maam we should remove electrons from 4s first then 3d right
13:51 mam two electrons need to be removed from 4s orbital
Yes she is removing directly from 'd' orbital, but outermost orbital is 's' orbital and she is not following Aufbau Principle..
if electrons are removed from 's' orbital , we will get correct no. of unpaired electrons..
Yes, 👍🏻
Ma'am please upload MCQs!!!
Mam Ni2+ correct aage idhe....but we have to remove the elctrons from 4S orbital so that there t
Will be 2 unpaired eletrons in 3d orbital .....and the answer will be 2.84BM..
Hello reply mam 1st 4S Alli electrons tagibekalva Niv nodudre 3d Alli tagitiddira
Ma'am electrons na nav modlu outer most shell enda tegibeku means from 4s then 3d enda
Mam do please MCQ's ..,,i'm waiting for ur session ..😢😢
mam for nickel 2 electrons will be removed from 4s not 3d
12:27 mam electron removed from outer most orbit or valence orbit i.e 4s
Mam we have to remove the electrons from the outermost orbit like 4s not from 3d orbit..... who are all agree 👇
Mam we have to remove in 4S with 2 electrpn
14:30 mam we do it like
Ni =28
Ni2+= 26
Ar + 8e
|11 |11| 11| 1| 1| un paired = 2e
n=2
Yaaa
Mam Ni+2, no of unpaired electrons is 2 ......
Literally just going through your important questions pdf for this chapter, thank you.
Ma'am we wil remove last two electrons in 3s orbital
spin only magnetic moment for Ni 2+ . configuration - 3d^8 4s^2 .hence = n=2 .2.82BM is correct answer
👍
Thanks ma'am for giving imp questions ☺️
Madam 5 marks important questions hele please 😊
Thank you so much mam it is really very much helpful..now I'll follow thus channel for KCET also 😊
Mam in lanthanoid contraction covalent character increases
Tq for your every videos mam❤😊
4:39 maam is it fine if we write H+ only instead of H2SO4?
Spin only magnetic moment of nickel, ಇದರಲ್ಲಿ s orbital ಇಂದ first two electrons remove madbeku ma'am
Waited for this 🎉
Tq mam... Mama mcQ plzz❤❤
THANK YOU VERY MUCH MA'AM, I REALLY HAVE A DISTINGUISHED RESPECT FOR PASSION DRIVEN TEACHERS LIKE YOU AND SIR...💪💪💪
Ma'am love from Sirsi uttarakannada ❤come to sirsi.... ❤

Mam app alli kottiro important questions matte section wise analysis mathra odidre yest marks barbahudu?
Yaradru reply madii
you can find n value in magnetic moment
n=atomic no--- oxidation state--- 18
if it is greater than 5 ,then then you can do 10--n
13:51 Outermost shell 4s alli electron remover madbeku
Ma'am your explanation is superb i could understand easily superb effective teaching hat's off ma'am
14:40 unpaired 6 electrons coz we remove electrons from s orbital and not from d orbital
Thank you mam full clear ❤❤😊
Mam ede tara partB video kuda uploard madiiii
Mam in calculating spin magnetic moment electrons are not lost from d subshell it is lost from outermost s subshell
Mam 2 electrons remove madbeku mam because of ni2+
Ma'am
In lanthanoid contraction covalent character of cations increases , does not decrease.
not all hero's wear capes some make online video lectures before exams🥺🥺
Thank u mam ❣️
You are the best ma'am 🎉❤🎉❤🎉❤🎉❤🎉
Covalent character of cation increases mam
I really loved ur teachings mam plz uploaded soon mcq from kolar district
Thank you ❤
i have all understood mam ...after listening your class...i will not study ...so understandable explanation😎😎😎😎😎
mam come to vijayanagara (hosapete)
20:24 covalent character of cation increase or decrease.?? mam😢.
Thank you maam 😊

Thank you mam ❤
Mam electrons remove from 4s orbital
To explain the chromate or dichromate, what should we explain?
Stop liking the comment and say😭
The dichromate ion consists of two tetrahedra sharing one corner.
The bond angle Cr-O-Cr is 126°.
Steps 😅
Thank you ma'am ❤
1st one mam.!! Love from Hubballi.! ❤️
I love ur teaching mam❤❤
Mam e chapter nali iste odkondre saka mam ? Tell me mam
we must apply 1st yr concept too electrons will come out from 4s orbital first
Mam please tell about the MCQ and FIB time is short mam ⏳
Super madam 😊 your all class super mam 👌👌
