Vedclass · Answer

(B) The orbital angular momentum of an electron in the $2s$-orbital is zero.For a given subshell with azimuthal quantum number $l$,the orbital angular momentum is given by the expression:$L = \frac{h}{2\pi} \sqrt{l(l+1)}$For $2s$ orbital,the azimuthal quantum number $l = 0$.Substituting the value of $l$ in the formula:$L = \frac{h}{2\pi} \sqrt{0(0+1)} = 0$

The orbital angular momentum of an electron in $2s$ orbitals is
