| Abstract | Abstract: The biennial review of atomic weight determinations, A r (E), and other cognate datahas warranted no changes for the standard atomic weights of the elements from that previouslypublished in the Table of Atomic Weights 1995 with the exception of a new footnote forlithium. The names for the transfermium elements with atomic numbers 101–109 have beenofficially adopted, and element 112 has been synthesized. Many elements in nonterrestrialmatter have isotopic compositions different from those in similar terrestrial substances thatmay affect their atomic weight. Some recent isotopic data on xenon and oxygen innonterrestrial materials are included in this report together with a discussion of the possibleprocesses causing these changes.INTRODUCTIONThe Commission on Atomic Weights and Isotopic Abundances met under the chairmanship of ProfessorL. Schultz from 24 to 26 August 1997, during the 39th IUPAC General Assembly in Geneva, Switzerland.The Commission decided to publish the report ‘Atomic Weights of the Elements 1997’ as presented hereand the report ‘Isotopic Compositions of the Elements 1997’ [1].The Commission has reviewed the literature over the previous two years since the last report onatomic weights and evaluated the published data on atomic weights and isotopic compositions onan element-by-element basis.
