Question

The magnitude of angular momentum of an electron occupying 3s atomic orbital is

• A. $\sqrt{2h}$
• B. $\sqrt{6h}$
• C. $\sqrt{3h}$
• D. 0

Hint:

The angular momentum of electrons in s orbitals is zero because the orbital angular momentum quantum number is zero.

Answer 1

The Correct Option is D

For an electron in an s orbital (\( l = 0 \)), the angular momentum is given by \[ L = \sqrt{l(l+1)}h, \] which is zero for \( l = 0 \).
