The biennial review of atomic-weight determinations and other cognate data has resulted in changes for the standard atomic weights of five elements. The atomic weight of bromine has changed from 79.904(1) to the interval [79.901, 79.907], germanium from 72.63(1) to 72.630(8), indium from ...
Variation in isotopic composition and atomic weight of bromine in selected bromine-bearing materials (modified from [10]). SMOB is Standard Mean Ocean Bromide [24]. Isotopic reference materials are designated by solid black circles. The δ81Br scale and the 81Br amount-fraction scale were matche...

Abstract: The biennial review of atomic-weight determinations and other cognate data has resulted in changes for the standard atomic weights of five elements. The atomic weight of bromine has changed from 79.904(1) to the interval [79.901, 79.907], germanium from ...
To date, the Commission provides the standard atomic weight as an interval for 14 elements: argon, boron, bromine, carbon, chlorine, hydrogen, lead, lithium, magnesium, nitrogen, oxygen, silicon, sulfur, and thallium [4, 18, 19]. For some elements, atomic weights calculated from published ...
when an uncertainty was added to copper and the uncertainties were lowered on bromine and silver. In 1967, an uncertainty was added for neon and the uncertainty for chromium was eliminated. Finally in 1969, this transition from a concept of a constant of nature was completed with the publicatio...
