element 118 (oganesson) was the most recently confirmed/named element (2016) and no new elements were added through 2024, so the iupac table lists 118 elements as of 2024., iupac (international union of pure and applied chemistry) periodic table of elements; as of 2024 the table contains 118 confirmed elements, 1 (hydrogen) to 118 (oganesson), per iupac's official periodic table and encyclopaedia britannica's periodic table entry, iupac (international union of pure and applied chemistry) periodic table of elements; element 118 (oganesson) was confirmed and named in 2016 and no new elements have been added since, so as of 2024 the periodic table contains 118 confirmed chemical elements, iupac (international union of pure and applied chemistry) periodic table of the elements, as published at https://iupac.org/what-we-do/periodic-table-of-elements/ — 118 confirmed elements (1 hydrogen through 118 oganesson), iupac (international union of pure and applied chemistry) periodic table of the elements, as published at iupac.org, listing 118 confirmed elements since 2016;
