Question

The angular momentum of the allowed orbits in a $H-$ like species is integral multiple of:

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

Answer 1

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

The angular momentum of allowed orbits in a $H-$like species is integral multiple of $\frac{h}{2\pi }$.
$\therefore$ Angular momentum $=mvr=n\frac{h}{2\pi }$
(where $n$ is the orbit number.)
