The size of the following species increases in the order

A

`Mg^(2+)ltNa^(+)ltF^(-)ltAl`

B

`F^(-)ltAlltNa^(+)gtMg^(2+)`

C

`AlltMg^(2+)ltF^(-)ltNa^(+)`

D

`Na^(+)ltAlltF^(-)ltMg^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Mg^(2+)ltNa^(+)ltF^(-)ltAl`
`F^(-)` has bigger size than `Mg^(2+)` and `Na^(+)` due to small nuclear charge.
