lonic radii (in `oversetoA`) of `As^(3+)`, `Sb^(3+)` and `Bi^(3+)` follow the order

A

`As^(3+) gt Sb^(3+) gt Bi^(3+)`

B

`Sb^(3+) gt Bi^(3+) gt As^(3+)`

C

`Bi^(3+) gt As^(3+) gt Sb^(3+)`

D

`Bi^(3+) gt Sb^(3+) gt As^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
D
In a Group, ionic radius increases from top to bottom. Hence, the order should be: `Bi^(3+) > Sb^(3+)>As^(3+)`.
