Answer

Brief Explanations:

Electron - affinity generally decreases down a group. Chlorine and bromine are in Group 17, and chlorine is above bromine. A more negative electron - affinity means a greater attraction for an added electron. Since chlorine has a stronger attraction for an added electron than bromine, chlorine's electron - affinity value is more negative.

Answer:

Chlorine’s electron affinity value is more negative than the electron affinity value of bromine.
