Vedclass · Answer

(A) For isoelectronic species,the ionic radius increases as the negative charge increases and decreases as the positive charge increases.All the given species $(C^{4-}, N^{3-}, O^{2-}, Mg^{2+})$ are isoelectronic with $10$ electrons.Among these,$C^{4-}$ has the highest negative charge,which results in the greatest inter-electronic repulsion and the weakest effective nuclear attraction.Therefore,$C^{4-}$ has the maximum ionic radius.

For which of the following ionic species would the radius be maximum?
