A metal (from Greek "μέταλλον" – métallon, "mine, quarry, metal") is an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable, ductile and shiny. The meaning of the term "metal" differs for various communities. Many elements and compounds that are not normally classified as metals become metallic under high pressures (see nonmetal#Metallic allotropes.)

Famous quotes containing the word metal:
“We are supposed to be the children of Seth; but Seth is too much of an effete nonentity to deserve ancestral regard. No, we are the sons of Cain, and with violence can be associated the attacks on sound, stone, wood and metal that produced civilisation.”
—Anthony Burgess (b. 1917)
