(a) How many sub-shells are associated with n = 4?(b) How many electrons will be present in the sub-shells having ms value of -1/2 for n = 4?

Answer»

When n = 4
l = 0,1,2,3.
l = 0; 4s- subshell
l = 1; 4p - subshell
l = 2;4d- subshell
l = 3; 4f - subshell
There are 4-subshells.
No. of electrons present in the subshells having ms value of 1/2 for n = 4 are 16.
