Question

Why does cl has more electron affinity than fluorine

Answer 1

Answer:

This is due to the reason explained below: Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. ... Since, energy released during the formation of Cl− (g) ion is more than that released in case of F−(g) ion, the electron affinity of chlorine is more than that of fluorine.
