  • Nonmetal

    In chemistry, a nonmetal (or nonmetal) is a chemical element that mostly lacks the characteristics of a metal.Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density.A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity.Chemically, nonmetals tend to have relatively high ionization energy
