The radii of F , `F^(-) , O ` and `O^(2)` are in the order

A

`O^(2-) gt O gt F^(-) gt F`

B

`F^(-) gt O^(2-) gt F gt O`

C

`O^(2-) gt F^(-) gt F gt O`

D

`O^(2-) gt F^(-) gt O gt F`

Verified by Experts

The correct Answer is:

D

Radii are in the following order
`O^(2-) gt F^(-) gt O gt F to `
`O^(2-)` and `F^(-)` are isoelectronic and O,F belong to the same period.
