Click the button that shows the correct relationship of the electron affinities of the elements bromine and chlorine.

Chlorine and bromine are both halogens, and chlorine’s electron affinity is more exothermic: about −349 kJ/mol compared with bromine’s roughly −325 kJ/mol. Because −349 is more negative than −325, chlorine’s electron affinity value is more negative. The correct choice is “Chlorine’s electron affinity value is more negative than the electron affinity value of bromine.”
