$0$ and $\sqrt{2} \frac{h}{2 \pi}$

Vedclass · Answer

(D) The orbital angular momentum is given by the formula $\sqrt{\ell(\ell+1)} \frac{h}{2 \pi}$.For the $2s$ orbital,the azimuthal quantum number $\ell = 0$.Therefore,the orbital angular momentum $= \sqrt{0(0+1)} \frac{h}{2 \pi} = 0$.For the $2p$ orbital,the azimuthal quantum number $\ell = 1$.Therefore,the orbital angular momentum $= \sqrt{1(1+1)} \frac{h}{2 \pi} = \sqrt{2} \frac{h}{2 \pi}$.

For an electron in $2s$ and $2p$ orbitals,the orbital angular momentum values,respectively,are $:$
