In chemistry, a metal (Μέταλλο)'s an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid's held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds. Definition Metals are sometimes described as… (More on Metallic)
