The biennial review of atomic-weight determinations and other cognate data has resulted in changes for the standard atomic weights of 19 elements. The standard atomic weights of four elements have been revised based on recent determinations of isotopic abundances in natural terrestrial materials (cadmium, molybdenum, selenium, and thorium), while the revision of 15 others is based on the 2012 Atomic Mass Evaluation (aluminium, arsenic, beryllium, caesium, cobalt, fluorine, gold, holmium, manganese, niobium, phosphorus, praseodymium, scandium, thulium, and yttrium). The Commission on Isotopic Abundances and Atomic Weights (ciaaw.org) also recommends the standard value for the natural terrestrial uranium isotope ratio, N(238U)/N(235U) = 137.8(1).
