Based on quantum mechanical formulations, the orbital angular momentum of an electron residing in a Atomic Structure Chemistry Question

Question

Based on quantum mechanical formulations, the orbital angular momentum of an electron residing in a $3p$ orbital is:

Answer: D

💡 Solution & Explanation

Orbital angular momentum is given by $\sqrt{l(l+1)} \frac{h}{2\pi}$. For any $p$ -orbital, $l=1$. Thus, momentum = $\sqrt{1(1+1)} \frac{h}{2\pi} = \sqrt{2} \frac{h}{2\pi}$.
