Question

Find the orbital angular momentum of $2p$-orbital in terms of $h/2\pi$ units.

Answer 1

orbital angular momentum is depend upon the Azimuthal quantum number

orbital Angular momentum $=\left(l\right(l+1){)}^{-1/2}nh/2\pi$

the value of l for $2p$ orbital is 1

So $=\left(1\right(1+1){)}^{-1/2}\times h/2\pi =h/\pi \times 2^{-1/2}$
