The transuranium elements (also known as transuranic elements) are the chemical elements with atomic numbers greater than 92, which is the atomic number of uranium. All of them are radioactively unstable and decay into other elements.

transuranium element, any of the chemical elements that lie beyond uranium in the periodic table —i.e., those with atomic numbers greater than 92. Twenty-six of these elements have been discovered and named or are awaiting confirmation of their discovery. Eleven of them, from neptunium through lawrencium, belong to the actinoid series.
In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded.
Das JRC Karlsruhe (ehemals Institut für Transurane (JRC-ITU), englische Version des Namens: Joint Research Centre – Institute for Transuranium Elements, JRC-ITU) ist ein Forschungsinstitut der Gemeinsamen Forschungsstelle der Europäischen Kommission . Das JRC der Europäischen Kommission hat seit dem 1. Juli 2016 eine neue Struktur [1].
17. Aug. 2020 · The transuranic elements and the island of stability. Kit Chapman. Published: 17 August 2020 https://doi.org/10.1098/rsta.2019.0535. Abstract. Since the 1930s the synthesis of nuclides too unstable to exist naturally on Earth has stretched the periodic table to 118 elements.
