uranium (U)

[yo̅o̅rā′nē·əm]
Etymology: planet Uranus
a heavy, radioactive metallic element. Its atomic number is 92; its atomic mass is 238.03. Uranium is the heaviest of the natural elements. Isotopes of uranium are used in nuclear power plants to provide neutrons for the nuclear reactions that result in release of energy. Uranium compounds have been used to impart an orange color to glass.
