setting up precise rules for how to name a new element.coordinating the naming of a new element, involving the research laboratory and allowing for public comments.assessing claims resulting in the validation and assignation of an element discovery.defining the structure of a temporary name and symbol.establishing the criteria for a new element discovery.In particular, IUPAC is directly involved in the following: IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input.

For elements that lack isotopes with a characteristic isotopic abundance in natural terrestrial samples, the mass number of the nuclide with the longest confirmed half-life is listed between square brackets. The latest release of the Periodic Table (dated ) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW), compiled as part of the 2021 Table of Standard Atomic Weights 2021.
