Question

chlorine is down in group than fluorine but it has high electron affinity than fluorine why???

Answer 1

Down a group, electron affinity typically decreases. This is because the atomic radius increases down a group. ... Fluorine, which is higher up the group then chlorine, has a lower electron affinity. This is because the electrons in the outermost shell of a fluorine atom are closer together.
