Answer
Metals have a shiny luster and are both malleable and ductile. Metals also have a high melting point, and are excellent conductors of heat and electricity.
Nonmetals, by comparison, do not tend to be as shiny. Nonmetals also tend to be quite brittle in solid state, have low density, and a low melting point. They do not conduct heat and electricity well.
