An element is composed of only one kind of atom and cannot be broken down chemically. A compound is composed of atoms of two or more elements chemically bonded, and are either ionic or molecular. An ion is an atom that has gained or lost one or more electrons, developing a negative or positive charge, respectively. A molecule is two or more atoms covalently bonded.
