What is the orbital angular momentum for electron in 2s orbital ?

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
Orbital angular momentum `=sqrt(l(1+1)).(h)/(2pi)`
for `2s l=0 = sqrt(0(0+1)) .(h)/(2pi)=0`
(for 2 s orbital l=0)
