Question

The orbital angular momentum for an $s$ electron will be given by:

• A. Zero
• B. $\frac{h}{2\pi }$
• C. $\sqrt{2}.\frac{h}{2\pi }$
• D. $\frac{1}{2}.\frac{h}{2\pi }$

Answer 1

The correct option is A Zero

For $s$ electron, $l=0$
We know,
$\text{Orbital angular momentum,}L=\sqrt{l(l+1)}\frac{h}{2\pi }$
$L=\sqrt{0(0+1)}\frac{h}{2\pi }=0$
