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 $l=2$
$2 d \rightarrow n \rightarrow 2$ 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.
