Arrange the following as stated: Increasing order of ionic size `N^(3-),Na^(oplus),F^(ɵ),O^(2-),Mg^(2+)` |
Answer» Correct Answer - `Mg^(2+) lt Na lt F^(ɵ) lt O^(2-) lt N^(3-)` The increasing order of ionic sizes is `Mg^(2+) lt Na lt F^(ɵ) lt O^(2-) lt N^(3-)` All of these are isoelectronic ions. In isoelectronic species, as the number of protons (atomic number) goes on increasing, size goes on decreasing due to stronger attraction on the electrons. |
