IUPAC Inorganic Chemistry Division

The Inorganic Chemistry Division of the International Union of Pure and Applied Chemistry (IUPAC), also known as Division II,[1] 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.[2] 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.[3][4][5][6] 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.[7]


The division has the following subcommittees and commissions:[8]

Former projects and other notable activities

The Inorganic Chemistry Division was a partner in the 2011 Global Chemistry Experiment "Water: A Chemical Solution" that took part during the International Year of Chemistry.[13][14]
