$X^{-}$ ion is larger in size than $X$ atom

Vedclass · Answer

(A) The correct statement is that the $X^{-}$ ion is larger in size than the $X$ atom.This occurs because,in an anion $(X^{-})$,the addition of an electron increases the electron-electron repulsion while the nuclear charge remains the same.Consequently,the effective nuclear charge per electron decreases,causing the electron cloud to expand and the ionic radius to become larger than the atomic radius of the neutral atom $X$.
