Vedclass · Answer

(A) The formula for orbital angular momentum is $\sqrt{\ell(\ell+1)} \frac{h}{2 \pi}$.For a $3s$ subshell,the azimuthal quantum number $\ell = 0$. Thus,the orbital angular momentum $= \sqrt{0(0+1)} \frac{h}{2 \pi} = 0$.For a $3p$ subshell,the azimuthal quantum number $\ell = 1$. Thus,the orbital angular momentum $= \sqrt{1(1+1)} \frac{h}{2 \pi} = \sqrt{2} \frac{h}{2 \pi} = \frac{h}{\sqrt{2} \pi}$.
