Question

How many electrons will be present in subshells having spin quantum number value of -1/2 for n=4?

Answer 1

If n = 4 then l = 3 and it forms 4f subshell.
It has 14 orbitals and each orbital can contain 2 electron in which one e- has +1/2 spin and one e- has -1/2 spin.Soo the no of electrons present in -1/2 spin of 4f orbital are 14.
I hope it will help u...
