Historio
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.

Aplikoj
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.
