Among the following which has higher electron affinity value ?
Open in App
Solution
The correct option is D Chlorine
Electron Affinity:
decreases down the group. Since the atomic size increases down the group,
electron affinity generally decreases(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.
