Transuranium element - Wikipedia
网页The transuranium (or transuranic) elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium. All of them are radioactively unstable and decay into other elements.

25.4: Transuranium Elements - Chemistry LibreTexts
网页2023年7月12日 · 25.4: Transuranium Elements. Page ID. Uranium (Z = 92) is the heaviest naturally occurring element. Consequently, all the elements with Z > 92, the transuranium elements, are artificial and have been prepared by bombarding suitable target nuclei with smaller particles. The first of the transuranium elements to be prepared was neptunium …
