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
With increase in nuclear charge, size decreases in isoelectronic ions.
`N ^(3-)(Z=7) gt O ^(2-) (Z=8)lt F ^(-) (Z=9)`
