Orbital Angular Momentum in 3s Orbital | JEE Main PYQ | Structure of Atom
Q. The orbital angular momentum of an electron in 3s orbital is (xh / 2π). The value of x is ________ (nearest integer).

Correct Answer: 0

Explanation

Orbital angular momentum of an electron is given by:

L = √[l(l + 1)] × (h / 2π)

For 3s orbital, azimuthal quantum number l = 0.

So,

L = √[0(0 + 1)] × (h / 2π) = 0

Hence, x = 0.
