The electron gain enthalpy of oxygen is `"______"` that of sulphur.

The second electron gain enthalpy of oxygen is

The electron gain enthalpy of oxygen is "…………………." than that of sulphur.

Why is the electron gain enthalpy of oxygen is less than that of sulphur?

Explain with reason : The negative electron gain enthalpy of oxygen is less than that of sulphur.

The electron gain enthalpy of noble gas is

(i) Why is theh electron-gain enthalpy of oxygen is less than that of sulphur? (ii) Arrange the following metal oxides in terms of ascending order of basicity: ZnO, MgO, CaO, CuO.

The negative electron gain enthalpy of oxgyen in less than that of sulphur . Explain

Generally electron gain enthalpy increases along a period and decreases down the group. But electron gain enthalpy of oxygen is -141 kJ//mol while that of sulphur is -200 kJ//mol . Explain.
