As we learnt

 

Variation of electron gain enthalpy with size of atom -

 

In general, the electron gain enthalpy value decreases (less negative) with increasing atomic radius.

- wherein

\bigtriangleup _{eg}H^{-}\:\:orE.A\:\propto \frac{1}{Atomic \:radius}

 

 Electron gain enthalpy decreases with increasing atomic radius
