The reason Bromine is more likely to exist as an anion than is potassium is because ________.
A)Bromine is bigger than potassium
B)Bromine has a greater ionization energy than potassium does
C)Bromine has a greater electron affinity than potassium does
D)Bromine is a liquid and potassium is a solid
E)Bromine is more metallic than potassium

Question

Quizplus · Accepted Answer

Bromine has a greater electron affinity than potassium, which means it is more likely to gain an electron and form an anion. Ionic compounds form when a metal atom donates an electron to a nonmetal atom, which becomes negatively charged and forms an anion. So, Bromine is more likely to exist as an anion than potassium because of its higher electron affinity.
