MCQ
The angular momentum of electron in $'d'$ orbital is equal to
  • A
    $2 \sqrt {3} \ \hbar$
  • B
    $0 \ \hbar$
  • ✓
    $\sqrt {6} \ \hbar$
  • D
    $\sqrt {2} \ \hbar$
✓

Answer

Correct option: C.
$\sqrt {6} \ \hbar$
c
Angular momentum $=\sqrt{l(l+1)} \hbar$

For $d$ orbital, $l=2$

Angular momentum $=\sqrt{2(2+1)} \hbar=\sqrt{6} \hbar$
