Metal

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:

    There is a lot of talk now about metal detectors and gun control. Both are good things. But they are no more a solution than forks and spoons are a solution to world hunger.
    Anna Quindlen (b. 1953)

    There were metal detectors on the staff-room doors and Hernandez usually had a drawer full of push-daggers, nunchuks, stun-guns, knucks, boot-knives, and whatever else the detectors had picked up. Like Friday morning at a South Miami high school.
    William Gibson (b. 1948)
