Uranium (U) is a metallic‚ silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors‚ but it also is utilized in the production of nuclear weapons. Because uranium is radioactive‚ it is constantly emitting particles and changing into other elements‚ like thorium. Uranium has a well-established radioactive decay chain. U-238 and U-235 (which has 143 neutrons) are the most common isotopes of uranium. Uranium naturally includes all three isotopes (U-238
