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

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

Assertion: magnitude of electron gain enthalpy of oxygen is less than that of fluorine but greater than that of nitrogen. Reason: Ionisation enthalpy order is as follows: N gt O lt E .

Assertion: magnitude of electron gain enthalpy of oxygen is less than that of fluorine but greater than that of nitrogen. Reason: Ionisation enthalpy order is as follows: N gt O lt F .

The negative electron gain enthalpy of fluorine is less than that of chlorine.

Assertion : The electron gain enthalpy of chlorine is less negative than that of fluorine. Reason : The fluorine atom is much smaller in size than that of chlorine.

Why is the electron gain enthalpy of O or F less than that of S or Cl?

Electron gain enthalpy of fluorine is less than that of chlorine - explain.

Electron gain enthalpy will be positive in

Assertion:For the elements O or F,the electron gain enthalpy is less negative than that of the succeeding element. Reason:Electron gain enthalpy becomes less negative as we go down a group.

The second electron gain enthalpies (in kJ mol^(-1) ) of oxygen and sulphur respectively are:
