Electron gain enthalpy values of the first four chalcogens are randomly given as -200 kJ/mole , -141 kJ/mole , -190 kJ/mole and 

-195 kJ/mole. Electron gain enthalpy of sulphur will be


 Electron gain enthalpy of O(-141 kJ/mole)<S(-200 kJ/mole)<Se(-195 kJ/mole)<Te(-190 kJ/mole);

Due to small size and inter electronic repulsions  EGE of oxygen very less;
