IUPAC Inorganic Chemistry Division

The Inorganic Chemistry Division of the International Union of Pure and Applied Chemistry (IUPAC), also known as Division II, deals with all aspects of inorganic chemistry, including materials and bioinorganic chemistry, and also with isotopes, atomic weights and the  periodic table. It furthermore advises the Chemical Nomenclature and Structure Representation Division (Division VIII) on issues dealing with inorganic compounds and materials. For the general public, the most visible result of the division's work is that it evaluates and advises the IUPAC on names and symbols proposed for new elements that have been approved for addition to the periodic table. For the scientific end educational community the work on isotopic abundances and atomic weights is of fundamental importance as these numbers are continuously checked and updated.

Subcommittees
The division has the following subcommittees and commissions:
 * Subcommittee on Isotopic Abundance Measurements
 * Interdivisional Subcommittee on Materials Chemistry
 * Subcommittee on Stable Isotope Reference Material Assessment
 * Commission on Isotopic Abundances and Atomic Weights (CIAAW)
