Solution

Orbital angular momentum $m v r = \frac{h}{2 π} \sqrt{l (l + 1)}$ .

Hence, it depends only on 'l'. l can have values ranging from 0 to (n-1)

(a) When l = 0, the subshell is s and orbital is spherical in shape.

(b) When l = 1, the subshell is p and orbital is dumb - bell shaped

(c) When l = 2, the subshell is d and orbital is double dumb-bell shaped.

(d) When l = 3, the subshell is f and orbital is complicated in shape.
