Anionic radius is higher than the corres...

Anionic radius is higher than the corresponding neutral atom. Give reason.

Text Solution

Verified by Experts

When an atom gain one or more electrons it forms anion. During the formation of anion, the number of orbital electrons become greater than the nuclear charge. Hence, the electrons are not strongly attracted by the lesser number of nuclear charges. Hence anionic radius is higher than the corresponding neutral atom.
