$F^{-}$

Vedclass · Answer

(B) The species $Na^{+}$,$Ne$,and $F^{-}$ are isoelectronic,meaning they all contain $10$ electrons.For isoelectronic species,the ionic radius decreases as the nuclear charge (number of protons) increases.$F^{-}$ has $9$ protons,$Ne$ has $10$ protons,and $Na^{+}$ has $11$ protons.Since $F^{-}$ has the lowest number of protons $(9)$,the effective nuclear attraction on the electrons is the weakest,resulting in the largest ionic radius.The order of size is $F^{-} > Ne > Na^{+}$.
