When the atom forms its most common ion, it loses three electrons, becoming the cation Al 3+. In general, metal atoms tend to lose electrons to form cations. Non-metal atoms tend to gain electrons and form anions. WebMetals conduct electricity because they have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom.
