Uranium was discovered in 1789 by the German chemist Martin Heinrich Klaproth.

In 1841, Eugène-Melchior Péligot isolated the first sample of uranium metal by heating uranium tetrachloride with potassium.

Antoine Henri Becquerel discovered radioactivity by using uranium in 1896. Named after the planet Uranus 110 1994 S. Hofmann, V. Ninov, F. P. Hessberger, P. Armbruster, H. Folger, G. Münzenberg, H. J. Schött, and others Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany. The name darmstadtium lies within the long established tradition of naming an element after the place of its discovery, Darmstadt, in Germany.

Uranium is toxic and highly radioactive
Uranium-235 was the first isotope that was found to be fissile
Uranium is used as fuel for nuclear power plants.

Uranium is used as a colorant in uranium glass, producing orange-red to lemon yellow hues.

It was also used for tinting and shading in early photography.

The major application of uranium in the military sector is in high-density penetrators.
