It is an actinoid.
There are 15 elements in the actinoid series, also known as the actinides. These elements follow actinium in the periodic table and include elements such as thorium, uranium, and plutonium.
1. Uranium is an example of an actinoid; also uranium is a solid metal, radioactive, a natural chemical element. 2. Leptons are elementary particles with a very small mass as: electrons, neutrinos and the corresponding antiparticles.
Uranium is an actinoid series element.

Mendelevium is an artificial chemical element, atomic number 101, metal, solid, radioactive, unstable, actinoid.
Fermium is an artificial element, solid, metal, radioactive, actinoid, atomic number 100.
It is an actinoid.
An actinoid is another word for an actinide, one of the fourteen chemical elements positioned under the lanthanides on the periodic table to which they have similar chemistry.
