Question

Explain why flourine forms a negative ion more easily than chlorine.​

Answer 1

The electron gain enthalpy of chlorine is more negative than fluorine. This is because fluorine is smaller in size than chlorine. Thus the extent of electron-electron repulsion would be more in fluorine than in chlorine. Because of this, the incoming electron would face more repulsion in fluorine than in chlorine.
