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

`1.36,1.40,1.70`

B

`1.36,1.71,1.40`

C

`1.71,1.40,1.36`

D

`1.71,1.36,1.40`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(Z,N^(-3),O^(-2),F^(-)),(e^(-),7,8,9),(Z//e,0.7,0.8,0.9):}`
Raduis `prop (1)/(Z//e)`
order of radius `= N^(-3) gt O^(-2) gt F^(-)`.
