Metal | Chemistry | Fandom
In chemistry, a metal is a chemical element whose atoms readily lose electrons to form positive ions, and form metallic bonds between metal atoms and ionic bonds between nonmetal atoms. A metal Alloy is a mixture of two or more elements in a solidified solution. Examples are Steel (Iron+Carbon, Bronze (Copper+Tin), and Electrum (Gold+Silver+::Copper).
