- Heavy, silvery-white metal -malleable and ductile > - Used as a fuel source in nuclear power plants > -Used in energy generation for both civilians and the military
 * Uranium was discovered in 1789 in Berlin, Germany by Martin Heinrich Klaproth. Klaproth had been studying mineral [|pitchblende (primary source of uranium)]. He dissolved the pitchblende in nitric acid, and added [|potash (fertilizer form of the element potassium)]. This resulted in a product with characteristics that were unknown to any other element. Klaproth concluded that he had discovered a new element ant named it after the recently discovered planet Uranus.
