What is the difference in the angular momentum associated with the electron in two successive orbits of a hydrogen atom?

A

` h//pi`

B

` h// 2pi`

C

` h//2`

D

` (n-1) h//2pi`

Text Solution

Verified by Experts

The correct Answer is:
B
Angular momentum for `n` and ( n+ 1) shellls are
` ( nh)/(2pi) and ( n+1) h/( 2 pi)`.
