Abstract
Atomic weights are periodically revised as our knowledge about them changes. On average, the standard atomic weight of an element is revised every 14 years, although some take longer before a change is required. Selenium, for example, had to wait almost 80 years before its standard atomic weight was revised in 2013 by the International Union of Pure and Applied Chemistry (Iupac) Commission on Isotopic Abundances and Atomic Weights (CIAAW).
