STD 11 - 3. Classification of elements and periodicity in properties — NEET STD 11 Science — Question

Since $X ^{-}$(negatively charged species has more electron density, hence it can give easily electron so its $IP$ is less than $X$ )

I$\varepsilon$ is greater than $\varepsilon$.A since in $\varepsilon . A$ of neutral species energy generally releases than in I$\varepsilon$ which require more energy to extract an electron.
