Yahoo Answers: Answers and Comments for What are ...

In chemistry, a metal is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations). Metals are usually inclined to form cations through electron loss, reacting with oxygen in the air to form oxides over times.
