Question

The negative value of electron gain enthalpy is less for flourine than for chlorine.

• A. True
• B. False

Answer 1

The correct option is A True

It is due to the small size of $F$ and high electronegativity the incoming $e^{-}$ suffers repulsion and hence has low negative value of $EGE$. Whereas in case of $Cl$, due to the bigger size of $Cl$ it can accommodate the incoming $e^{-}$ very easily and hence has a high negative value of $EGE$.
