The International Union of Pure and Applied Chemistry (IUPAC) is an international federation of organizations that represents chemists in individual countries. IUPAC is best known for its works standardizing nomenclature in chemistry and other fields of science.
- 7.6: The Stock System of Nomenclature
- Naming compounds that involve transition metal cations necessitates that use of the Stock system.
- 7.9: Polyatomic Ions
- Many materials exist as simply binary compounds composed of a metal cation and a nonmetal anion, with each ion consisting of only one type of atom. Other combinations of atoms also exist, either larger ionic complexes or complete molecules. Some of the most useful materials we work with contain polyatomic ions.
