Vedclass · Answer

(B) Ionization energy is the energy required to remove an electron from a neutral atom or ion. $1$. Neutral atoms have higher ionization energy than their corresponding anions because removing an electron from a negatively charged species is easier due to electron-electron repulsion. Thus,$F > F^{-}$ and $Cl > Cl^{-}$. $2$. Comparing neutral atoms,$F$ has a smaller atomic size than $Cl$,so the valence electrons in $F$ are more strongly attracted to the nucleus,making $F > Cl$. $3$. Comparing anions,$F^{-}$ has a smaller size than $Cl^{-}$,so $F^{-} > Cl^{-}$. Combining these,the order of ionization energy is $F > Cl > Cl^{-} > F^{-}$.
