Assessment of Fundamental Understanding of Isotopic Abundances and Atomic Weights
The International Commission on Atomic Weights was originally established in the latter part of the nineteenth century. Questions have been raised about the direction that the commission should take in the twenty-first century. Some of these questions include Who constitutes the audience for the information provided by the commission? At what time intervals is the information needed by the audience? Do synthetic elements require an atomic weight value and if so, how should these values be determined? Is a new definition of atomic weight needed and how should the uncertainties and the variation in nature of the values of the atomic weights and the isotopic abundances of the various chemical elements be treated in a consistent manner? A project has been approved to help answer some of these and related questions and to provide advice to the commission for its future efforts within IUPAC. The task group, chaired by Norman E. Holden, includes Tyler Coplen, John Karl Bohlke, Paul De Bièvre, John de Laeter, and Etienne Roth.
