MCQ
The maximum number of electrons in subshell is given by the expression :
- ✓$4l + 2$
- B$4l - 2$
- C$2l + 1$
- D$2n^2$
✓
Answer
Correct option: A.
$4l + 2$
a
The maximum number of electrons in a given subshell is given by $2(2l+1)$ or $(4l+2)$
The maximum number of electrons in a given subshell is given by $2(2l+1)$ or $(4l+2)$
Thus,
$s$ - subshell $(1=0)$ contains $2$ electrons.
$p$ - subshell $(1=1)$ contains $6$ electrons.
$d$ - subshell $(1=2)$ contains $10$ electrons.
$f$ - subshell $(1=3)$ contains $14$ electrons.
