Transuranium element
Also known as: Transuranic element
- 1Transuranium elements have an atomic number greater than 92.
- 2All members of this group are radioactively unstable.
- 3They are primarily synthetic elements.
- 4Neptunium and plutonium are the only transuranium elements found in trace amounts in nature.
The transuranium elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium.

Chemical classification
Fermium is a transuranium element, meaning it has an atomic number greater than 92 and is produced synthetically.
Transuranium elements are defined as chemical elements with an atomic number greater than 92, which corresponds to the element uranium. Because of their high atomic numbers, all of these elements are radioactively unstable and undergo decay into other elements.

These two elements have been identified in trace amounts within naturally occurring uranium ore, but otherwise, the entire group must be created through artificial processes.
