What is the correct oder of electron gain enthalpy of Cl, F, Te, Po

Electron gain enthalpy values of the elements are given below in $kJ / mol$,

$\begin{cases}F & Cl & \text{Te} & \text{Po} \\ - 333 & - 349 & - 190 & - 174 .\end{cases}$

Down the group electron affinity decreases. The size of fluorine atom is small. The addition of electron to small fluorine atom results in electron-electron repulsions. Hence, fluorine has less electron affinity than chlorine.

Hence, the correct order is

$Cl > F > {Te}_{} > PO$
