Uranium | Definition, Properties, Uses, & Facts - Britannica
Uranium, radioactive chemical element of the actinoid series of the periodic table, atomic number 92. It is an important nuclear fuel.
Uranium (U) is a metallic, silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors.
Like all other actinides, uranium is “radioactive” – it decays over time and releases energy in the process. Its special properties make uranium ...
