Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions: Nonmetal + Metal -> Salt [3Br_{2(l)} + 2Al_{(s)} rightarrow 2AlBr_{3(s)}]
