Question

The radii of $F,F^{-},O$ and $O^{- 2}$ are in the order of

$O^{2 -} > F^{-} > O > F$

$O^{2 -} > F^{-} > F > O$

$F^{-} > O^{2 -} > F > O$

$O^{2 -} > O > F^{-} > F$

Answer

$O^{2 -} > F^{-} > O > F$

Explanation

Solution

Atomic radius decreases on going from left to right in a period. Thus size of $O > F$ . As $O^{2 -}$ and $F^{-}$ are isoelectronic, therefore, size of $O^{2 -} > F^{-}.$
