Standard and conventional atomic weights 2016 abridged to four significant digits 2016 four-figure standard and conventional atomic weights of the chemical elements Categories: Data; Tags: NA, USGS Science Data Catalog (SDC), atomic weight, atomic weight interval, atomic weights, All tags... conventional atomic weight, standard atomic weights, Fewer tags Tables and charts for isotope-abundance variations and atomic weights of selected elements: 2016 (Ver. 1.1, May 2018) Twelve chemical elements have intervals for their standard atomic weights, namely hydrogen, lithium, boron, carbon, nitrogen, oxygen, magnesium, silicon, sulfur, chlorine, bromine and thallium. Isotopic abundances, isotope-delta values, and atomic weights for each of the lower and upper bounds of materials and compounds of these 12 elements are tabulated. Version 1.1 is the most current version. Categories: Data, Data Release - Revised; Tags: NA, USGS Science Data Catalog (SDC), atomic weights, isotopic abundances Four-place table of standard atomic weight values of hydrogen through uranium compared since 1961 Four-figure standard atomic weights of the chemical elements are shown for 1961, 1975, 1983, 2007, 2009, 2011, 2013, 2015, and the current value for 2016. Values between 1975 and 2015 are only shown when there is a change in value with respect to the previous column.
