History

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

Discoverers	Martin Klaproth
Discovery Location	Germany
Discovery Year	1789
Etymology (Name Origin)	Named for the planet Uranus.
Pronunciation	yoo-RAY-ni-em (English)

Uranium is toxic and highly radioactive

Uranium-235 was the first isotope that was found to be fissile

Uses

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. For many centuries it was used as a pigment for glass. Now it is used as a fuel in nuclear reactors and in bombs.

Sources

Occurs in many rocks, but in large amounts only in such minerals as pitchblende and carnotite.
