1.

Which one of the following is the smallest in size?A. `N^(3-)`B. `O^(2-)`C. `F^(ɵ)`D. `Na^(ɵ)`

Answer» Correct Answer - D
All of these are isoelectronic ions (10 electrons).
In isolectronic species, as the number of protons (atomic number) goes on increasing, size goes on decreasing due to stronger attraction on the electrons (Z for N, O, F and Na=7, 8, 9 and 11)
