Ionic Bonding Formation of Ionic Compounds An ion is an atom or a group of atoms possessing a net electrical charge. Ions come in two basic types: 1. positive (+) ions or cations These atoms have lost 1 or more electrons. 2. negative (-) ions or anions These atoms have gained 1 or more electrons. Formation of Ionic Compounds Monatomic ions consist of one atom. Examples: Na + , Ca 2+ , Al 3+ - cations Cl - , O 2- , N 3- -anions Polyatomic ions contain more than one atom.

Unformatted text preview: NH 4 +- cation NO 2-,CO 3 2-, SO 4 2-- anions Formation of Ionic Compounds Ionic bonds are formed by the attraction between cations and anions, usually, to form solids. Commonly, metals react with nonmetals to form ionic compounds. The formation of NaCl is one example of an ionic compound formation.
