Question

Oxygen has less negative electron gain enthalpy than sulphur. Why?

✓

Answer

Oxygen has a smaller atomic size than sulphur.
It is more electronegative than sulphur.
It has a larger electron density.
Due to high electron density, oxygen does not accept the incoming electron easily and therefore has less electron gain enthalpy than sulphur.
