Question

The minimum angular momentum of electron of hydrogen atom in stationary orbit is

• A. $\frac{h}{2\pi }$
• B. $\frac{3h}{2\pi }$
• C. $\frac{h}{4\pi }$
• D. $\frac{5h}{2\pi }$

Answer 1

The correct option is A $\frac{h}{2\pi }$

For stationary orbits
$L=\frac{nh}{2\pi }$
$L_{min}=\frac{h}{2\pi }$
