MCQ
Which of the following subshell can accommodate as many as $10$ electrons?
  • A
    $2d$
  • ✓
    $3d$
  • C
    $3dxy$
  • D
    $3dz^2$
✓

Answer

Correct option: B.
$3d$
b
$2 d \rightarrow n \rightarrow 2$ and $l=2$

This subshell does not exist.

$3 d \rightarrow n=3$ and $l=2$

$3 d$ subshell

No. of orbital $=2 l+1=5$

Number of electron $=2 \times 5=10$

$3 d_{x y}$ and $3 d_{z^2}$ have maximum $2$ electron.
