The radius of which of the hydrated ion is the highest?

A

` Li_((aq))^(oplus)`

B

`Na_((aq))^(oplus)`

C

`K_((aq))^(oplus)`

D

`Rb_((aq))^(oplus)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Li^(oplus)` ion having the smallest size and the highest charge density is the most hydrated alkali metal and thus the size of `[Li(H_2O)_x ]^(oplus) or Li^(oplus)` (aq) is the highest
