In which one of the following pairs is the radius of the second species greater than that of the first?A. `Na, Mg`B. `Ba^(2+), Sr^(2+)`C. `O^(2-), N^(3-)`D. `Li^(+),Be^(2+)` |
|
Answer» Correct Answer - C Both `O^(2-)`and `N^(3-)`are isoelectronic. For such species, size increases with increase of negative charge. Moreover the nuclear charge of `N^(3-)` is less than that of `O^(2-)`. |
