Answer

Brief Explanations:

Electron - affinity is the energy change when an electron is added to a neutral atom in the gas phase. Halogens have high electron - affinities. Bromine (Br) is a halogen, while sodium (Na) is an alkali metal, aluminum (Al) is a metal, and sulfur (S) is a non - metal. Halogens have a strong tendency to gain an electron to achieve a stable noble - gas electron configuration, releasing a large amount of energy.

Answer:

C. Br
