Vedclass · Answer

(C) All the given ions $(C^{4-}, N^{3-}, O^{2-}, F^{-})$ are isoelectronic species,as they all contain $10$ electrons.For isoelectronic species,the ionic radius decreases as the nuclear charge (atomic number) increases.The atomic numbers are: $C = 6, N = 7, O = 8, F = 9$.Since $F^{-}$ has the highest nuclear charge $(Z = 9)$,it exerts the strongest attraction on the electrons,resulting in the smallest ionic radius.

Which of the following ions is the smallest in size?
