OpenStudy (zale101):

An Ion is a molecule that actively gains or looses one or more valance electrons. There's cations and anion. Cations are positively charged electrons, and are formed when it has more protons than electrons. Anions are negatively charged ions and are formed when it has more electrons than neutrons. Cations are the metal elements in ionic form, and anions are nonmetal elements in ionic form. A cation and an anion combined forms an ionic compound ionically bonded together.
