Nonmetal: The elements have a tendency to accept the electron and form anions called nonmetal. Example of nonmetal: Cl, Br, I etc. As oxygen has a tendency to accept the electron and form anion. So oxygen behaves as nonmetal. Oxygen is the most abundant nonmetal on the earth. Hence, oxygen is nonmetal. Suggest Corrections.
