How many chemical elements had IUPAC-approved names at the end of 2024? Answer with the whole number only.
Answer
118
- IUPAC-approved names at end of 2024
- Count the 118 recognized chemical elements in the IUPAC periodic table; the final four names (elements 113, 115, 117, and 118) were approved in 2016, completing the named set, with no later elements added by the end of 2024.

- iupac.org, en.wikipedia.org, iupac (international union of pure and applied chemistry) periodic table of the elements, as published at iupac.org; names for elements 113, 115, 117, 118 (nihonium, moscovium, tennessine, oganesson) were approved by iupac on 2016-11-28, completing the set of 118 approved element names, which remained unchanged through end of 2024, iupac announcement of 28 nov 2016 naming elements 113 (nihonium), 115 (moscovium), 117 (tennessine), 118 (oganesson); the iupac periodic table lists 118 named elements (also wikipedia, 'periodic table' and 'oganesson'), iupac periodic table of elements (https://iupac.org/what-we-do/periodic-table-of-elements/) listing all 118 named elements, with element 118 (oganesson) approved/named in 2016 per iupac's official announcement; no elements beyond 118 have been synthesized or named as of end of 2024, iupac periodic table of elements (https://iupac.org/what-we-do/periodic-table-of-elements/); iupac announcement that names for elements 113, 115, 117, and 118 were approved (https://iupac.org/iupac-announces-the-names-of-the-elements-113-115-117-and-118/), iupac periodic table of elements (iupac.org) and iupac 2016 announcement naming elements 113 (nihonium), 115 (moscovium), 117 (tennessine), and 118 (oganesson), completing the table through period 7;
