Since the atomic size increases down the group, electron affinity generally decreases (At < I < Br < F < Cl). An electron will not be as attracted to the nucleus, resulting in a low electron affinity. However, fluorine has a lower electron affinity than chlorine. This can be explained by the small size of fluorine, compared to chlorine.
Halogen | Electron Affinity (kJ/mol) |
---|---|
Fluorine | -328.0 |
Chlorine | -349.0 |
Bromine | -324.6 |
Iodine | -295.2 |
Astatine | -270.1 |
