What are the values of the orbital angular momentum of an electron in the orbitals `1s,3s,3d` and `2p`:-
(a). `0,0sqrt(6h),sqrt(2h)`
(b). `1,1sqrt(4h),sqrt(2h)`
(c). `0,1sqrt(6h),sqrt(3h)`
(d). `0,0sqrt(20h),sqrt(6)`

Options

A. `0.0,sqrt(6)h,sqrt(2)h`
B. `1,1,sqrt(4)h,sqrt(2)h`
C. `0,1,sqrt(6)h,sqrt(3)h`
D. `0,0,sqrt(20)h,sqrt(6)h`

Answer

A

Explanation

Orbital angular momentum `=sqrt(l(l+1))(h)/(2pi)=sqrt(l(l+1))h`
