All are correct

Vedclass · Answer

(D) $1$. $IP$ of $X_{(g)}^{+} > IP$ of $X_{(g)}$: Since the effective nuclear charge $(Z_{eff})$ of $X^{+}$ is greater than that of $X$,more energy is required to remove an electron from $X^{+}$.$2$. $IP$ of $X_{(g)} > IP$ of $X_{(g)}^{-}$: $X^{-}$ has higher electron density and greater inter-electronic repulsion,making it easier to remove an electron compared to the neutral atom $X$.$3$. $IP$ of $X_{(g)} > E.A$ of $X_{(g)}$: Ionization Potential $(IP)$ is the energy required to remove an electron,which is always positive,whereas Electron Affinity $(E.A)$ is the energy released when an electron is added,which is typically smaller in magnitude.Therefore,all statements are correct.
