MCQ
The smallest among the following ions is
- A$N{a^ + }$
- B$M{g^{ + 2}}$
- C$B{a^{2 + }}$
- ✓$A{l^{3 + }}$
✓
Answer
Correct option: D.
$A{l^{3 + }}$
d
$(d)$ The size of an species decreases with increasing nuclear charge because the attraction for the electrons increases. Thus $A{l^{3 + }}$is smaller in size.
