The negative electron gain enthalpy of F is less/more than Cl.

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

Which of the following pairs of elements would have a more negative electron gain enthalpy? i) O or N ii) F or Cl

Explain: Electron gain enthalpy of chlorine is more negative than fluorine.

Would you expect the second electron gain enthalpy of O. as positive, more negative or less. negative than the first ? Justify your answer.

Although electron gain enthalpy of fluorine is less negative as compared to chlorine, fluorine is a stronger oxidising agent than chlorine. Why ?
