MCQ
If $M^{+3}$ has configuration $[Ar]3d^{10}$ then $M$ belongs to :-
- A$s - block$
- ✓$p - block$
- C$d - block$
- D$f - block$
✓
Answer
Correct option: B.
$p - block$
b
$M^{+3}=[\mathrm{Ar}] 3 \mathrm{d}^{10}$
$M^{+3}=[\mathrm{Ar}] 3 \mathrm{d}^{10}$
$M=[\mathrm{Ar}] 3 \mathrm{d}^{10} 4 \mathrm{s}^{2} 4 \mathrm{p}^{1}$
