Atomic Weights of the Elements 1997

R. D. Vocke, Jr.

Abstract: The biennial review of atomic weight determinations, Ar(E), and other cognate data has warranted no changes for the standard atomic weights of the elements from that previously published in the Table of Atomic Weights 1995 with the exception of a new footnote for lithium. The names for the transfermium elements with atomic numbers 101 to 109 have been officially adopted, and element 112 has been synthesized. Many elements in non-terrestrial matter have isotopic compositions different from those in similar terrestrial substances that may affect their atomic weight. Some recent isotopic data on xenon and oxygen in non-terrestrial materials are included in this report together with a discussion of the possible processes causing these changes.
