The minimum orbital angular momentum of ...

The minimum orbital angular momentum of the electron in a hydrogen atom is

A

h

B

`(h)/(2)`

C

`(h)/(2pi)`

D

`(h)/(lamda)`

Text Solution

Verified by Experts

The correct Answer is:
C
Orbital angular momentum `=(nh)/(2pi)` for H-atom
Therefore, minimum value of `L=(h)/(2pi)` `(for n=1)`
