Question

Chlorine has the Highest Electron Affinity in the periodic table (Even more than Fluorine). Then how Fluorine is the most Electronegative?

Answer 1

Electron affinity of chlorine is higher than that of flourine. This results due to the small size of fluorine making greater electron-electron repulsion than how it does in chlorine. This in turn, makes it for electron affinity of chlorine being higher than that of flourine.
