Question

The minimum angular momentum that can be possessed by an electron in hydrogen atom is:

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

Answer 1

Answer: (C)

$\frac{h}{2\pi }$

The angular momentum that can be possessed by an electron in the hydrogen atom is given as; $\frac{nh}{2\pi }$;

where n = orbit in which electron is revolving.

So, for minimum angular momentum, $n=1$, therefore, the minimum angular momentum is $\frac{h}{2\pi }$.

Hence, option $C$ is correct.
