Atomic weights of the elements 2001
MetadataShow full item record
The biennial review of atomic-weight, Ar(E), determinations and other cognate data have resulted in changes for the standard atomic weights of the following elements:from tozinc 65.39 0.0265.409 0.004krypton 83.80 0.0183.798 0.002molybdenum95.94 0.0195.94 0.02dysprosium162.50 0.03162.500 0.001Presented are updated tables of the standard atomic weights and their uncertainties estimated by combining experimental uncertainties and terrestrial variabilities. In addition, this report again contains an updated table of relative atomic mass values and half-lives of selected radioisotopes. Changes in the evaluated isotope abundance values from those published in 1997 are relatively minor and will be published in a major review of each element in 2003.Many elements have a different isotopic composition in some non-terrestrial materials. Some recent data on parent nuclides that might affect isotope abundances or atomic-weight values are included in this report for the information of the interested scientific community.

The atomic weight of bromine has changed from 79.904(1) to the interval ...
Additive single atom values for thermodynamics I: Volumes, entropies, heat capacities of ionic solidsGlasser, Leslie (2022)In an earlier simple “group contribution” method, molar volumes of organic and inorganic materials were predicted by summing optimised single atom values weighted according to the molecular formula. We here first revisit ...
Additive single atom values for thermodynamics II: Enthalpies, entropies and Gibbs energies for formation of ionic solidsGlasser, Leslie (2022)In part I of this series we established optimised sum values, for each of the chemical elements, of formula volumes, of absolute entropies, and of constant pressure heat capacities, together with their temperature ...
