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 114...
The latest evaluation of atomic weight determinations and other cognate data has warranted five changes for the standard atomic weights of the elements, [A.sub.r](E), from those published previously in the Table of Atomic Weights 2005. The revised standard atomic weight of nickel, [A.sub.r]...
The atomic weights of these 10 elements now will be expressed as intervals, having upper and lower bounds, reflected to more accurately convey this variation in atomic weight. The changes to be made to the Table of Standard Atomic Weights have been published inPure and Applied Chemistryand a ...
