The ionic radii of N^(3-), O^(2-) and F^...

The ionic radii of `N^(3-), O^(2-)` and `F^(-)` are respectively given by:

A

`1.71,1.40` and `1.36`

B

`1.71,1.36` and `1.40`

C

`1.36,1.40` and `1.71`

D

`1.36,1.71` and `1.40`

Text Solution

Verified by Experts

The correct Answer is:
A
For isoelectronic species, size of anion increases as negative charge increases. Thus the correct order is
`underset((1.71))(N^(3-)) gt underset((1.40))(O^(2-)) gt underset((1.36))(F^(-))`
