Vedclass · Answer

(C) Isoelectronic species are those that have the same number of electrons.For isoelectronic species,the ionic radius decreases as the nuclear charge (number of protons) increases.In option $C$,both $F^{-}$ and $Na^{+}$ have $10$ electrons.$F^{-}$ has $9$ protons,while $Na^{+}$ has $11$ protons.Since $F^{-}$ has fewer protons to attract the same number of electrons,it has a larger ionic radius than $Na^{+}$.Therefore,$F^{-}$ is larger than $Na^{+}$.
