Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

check
you have to learn different contribution of orbital and then use this after pairing of orbitals
why we don't take last electron,?
we can't take the electron to be considered
and also we don't take the electron contribution which falls after the considered electron
got this Anand?
please tell me in case of Zinc
how to make groups?
ok wait
1s (2s 2p) (3s 3p) (3d)(4s 4p) like that
what will be sree. const. value?
they becoming more than n-2
for which you have to find i.e for 3d or 4s ...this must be mentioned in ques
4s
for electron in 4s
yes wait
see anand
for 3d check
see the difference and ask if still any doubt
yes
got it ,thanku sir🙏🏻
so first you make them in group and learn the contribution and then find screening constant and after that Zeff =Z- screening constant
😊👍
