WebA nonmetal An element that exists in various colors and phases, is brittle, and does not conduct electricity or heat well. is an element that is brittle when solid, does not conduct electricity or heat very well, and cannot be made into thin sheets or wires (Figure 1.5 "Semimetals"). Nonmetals also exist in a variety of phases and colors at ... WebA non-metal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Physically, a nonmetal tends to have a relatively low melting point, boiling point and density. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity and electro-negativity. ...
