The orbital angular momentum for an el...

The orbital angular momentum for an electron revolving in an orbit is given by `sqrt(l(l + 1))(h)/(2pi)`. What is the momentum of an s-electron?

A

`+(1)/(2).(h)/(2pi)`

B

zero

C

`(h)/(2pi)`

D

`sqrt(2).(h)/(2pi)`

Text Solution

Verified by Experts

The correct Answer is:
B
For an electron in s-subshell, l = 0
`:.` Orbital angular momentum
`= sqrt(0(0+1)) (h)/(2pi)` = zero
