Arrange the following in order of increasing radii:
(b) $M g^{2 +}, M g, M g^{+}$

Open in App

Solution

In cation as the attraction force between the electrons and the nucleus is greater which results in the decrease in atomic radii.

Therefore, the size of an atom becomes greater than a cation.

Hence, the increasing order of radii is $M g^{2 +} < M g^{+} < M g$ .
