Orbital angular momentum depends on .........

Options

A. l
B. n and l
C. n and m
D. m and s

Answer

A

Explanation

Orbital angular momentum mvr = `h/(2pi)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.
