(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 $$- \dfrac{1}{2}$$ for n = 4?

##### Solution :-

(a) n = 4 (Given)

For some value of ‘n’, the values of ‘l’ range from 0 to (n – 1).

Here, the possible values of l are 0, 1, 2, and 3

Therefore, a total of 4 subshells are possible when n=4: the s, p, d and f subshells.

(b) No. orbitals in the nth shell = n2

For n = 4

Therefore, the total no. orbitals when n = 4 is 16

If each orbital fully occupied, each orbital will have 1 electron with ms value of $$-\dfrac{1}{2}$$.

Therefore, total no. electrons with an ms value of $$(-\dfrac{1}{2})$$ is 16.
