Electron gain enthalpy of Cl is more negative than F though electronegativity of F is greater than 'Cl'- Explain.

F is more electronegative than Cl, but electron-gain enthalpy of Cl is greater than that of F. explain.

Electron gain enthalpy of N is less than that of O. explain.

Ionisationn enthalpy of Be is greater than that of B-why?

Electron-gain enthalpy value of Cu is negative while that of Zn is positive explain?
