The metallic elements share certain characteristics. They are generally shiny and conductive. Many metals are silver or grey. Many are malleable and ductile. The nonmetals in the periodic table, however, represent a great deal of variety. Some are gases, some are solids, and one is a liquid. They include the most reactive and least reactive element.
