MCQ
The value of magnetic quantum number of the outermost electron of $\mathrm{Zn}^{+}$ion is ..... .
- A$1$
- ✓$0$
- C$3$
- D$2$
✓
Answer
Correct option: B.
$0$
b
$\mathrm{Zn}^{+} \rightarrow 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{~s}^{2} 3 \mathrm{p}^{6} 3 \mathrm{~d}^{10} 4 \mathrm{~s}^{1}$
$\mathrm{Zn}^{+} \rightarrow 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{~s}^{2} 3 \mathrm{p}^{6} 3 \mathrm{~d}^{10} 4 \mathrm{~s}^{1}$
Outermost electron is in $4 \,\mathrm{~s}$ subshell $\mathrm{m}=0$
