Uranium is a naturally occurring radioactive chemical element with the symbol U and atomic number 92. It is a silvery-white metal that chemically resembles niobium and tantalum. Uranium is almost always found in combination with other elements in minerals. It is the heaviest naturally occurring element and the principal fissile component of nuclear weapons.<\/p>\n<p>Mercury is a chemical element with the symbol Hg and atomic number 80.
