MCQ
All electrons on the $4p$ sub-shell must be characterized by the quantum number $(s)$
- A$n = 4,\,m = 0,\,s = \pm \frac{1}{2}$
- ✓$l = 1$
- C$l = 0,\,s = \pm \frac{1}{2}$
- D$s = \pm \frac{1}{2}$
✓
Answer
Correct option: B.
$l = 1$
b
$n=4, m=0$
$n=4, m=0$
$s=\pm 1 / 2$
$l=1 \quad s=0, s=\pm 1 / 2$
$s=\pm 1 / 2$
