Uranium (U) Element Properties
Atomic Mass 238.0289
Atomic Number 92
Name Origins Named after the planet Uranus.
Year Discovered 1789
Discovery Credits Discovered by M. H. Klaproth at Berlin, German; isolated in 1841 by E. M. Pleigot at Paris, France
Remarks Radioactive silvery metal. malleable, ductile, and tarnishes in air. Attacked by steam and acids but not by alkalis. Used as nuclear fuel and in nuclear weapons.

Diagnostic tests: 
Uranium is usually detected by radioactivity (due, in part, to the daughter elements such as radium). Thorium is also naturally radioactive; however, many uranium minerals are generally yellow or green and fluorescent.

With a borax bead test in the oxidizing flame, the bead is yellow to brownish red color while hot and is colorless to yellow when cold. This test is very similar to iron.

The Na2(NH4)(PO4) bead  test for uranium is a much better test, under oxidizing conditions the bead is clear yellow (hot) yielding slightly greenish yellow on cooling. In the reducing flame, it becomes a fine green color when hot or cold.
