MCQ
Which of the following has the smallest size
- A$N{a^ + }$
- ✓$M{g^{ + 2}}$
- C$C{l^ - }$
- D${F^ - }$
✓
Answer
Correct option: B.
$M{g^{ + 2}}$
b
(b)As the nuclear charge per ${e^ - }$ is maximum in $M{g^{ + 2}}$, it has smallest size among $N{a^ + },\,\,M{g^{ + 2}},\,\,C{l^ - }$ and ${F^ - }$.
(b)As the nuclear charge per ${e^ - }$ is maximum in $M{g^{ + 2}}$, it has smallest size among $N{a^ + },\,\,M{g^{ + 2}},\,\,C{l^ - }$ and ${F^ - }$.
