Oi towet sitei cottuioule tatit1. electron group all higher groups same group group with (n - 1)|group with (n -2) 1s 0 0.30 0 0 ns, np 0.35 0.85 1.00 nd, nf 0.

what's your doubt in this?

see

please ask if any doubt

confused between distinguishing n, n-1,n-2

ourtmost shell is n...valence shell

n-1 is next inner to valence shell...that is penultimate shell

n-2 is anti penultimate shell

so for which electron you have to find screening constant accordingly you take n,n-1,n-2

now got dear student??

IN case of B we take 2s, 2p as n

yes

as if you have to find screening constant of p electrons in boron

but IN case of Ti we do not consider 3s, 3p

as n shell why

yes,first you have to make a grouping of these

done

1s, 2s,2p 3s,3p 3d like these

next

if you have to consider d electron for screening constant then n= the period in which that d electron lies

n-1 inner to that

n-2 next inner

see once my attached image...

3s, 3p as n-1

is it so

for d electrons ...only n is taken and all other lower orbitals shields same...but for s and p orbitals n-1,n-2 cases comes

D is considered as n

yes

okk tysm

you welcome😊

I Am getting confused in Slater's rule even after learning the rules some questions are solved but most answers comes to be false

okay wait.. i think need to clear more concept

yes starting form ( n-2) and (n-1 )

check this video https://youtu.be/SXk43GQnETo

you can share your question so we can clear your doubt where your actually getting problem

okk
