Metal

In chemistry, the term ''base metal'' is used informally to refer to a metal that oxidizes or corrodes relatively easily, and reacts variably with dilute hydrochloric acid (HCl) to form hydrogen.Examples include iron, nickel, lead and zinc.Copper is considered a base metal as it oxidizes relatively easily, although it does not react with HCl.
