Isotope dating of rocks file profile
Research by Otto Hahn, Lise Meitner, Enrico Fermi and others, such as J.Robert Oppenheimer starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war.Uranium glass fluoresces green in ultraviolet light.
It has a Mohs hardness of 6, sufficient to scratch glass and approximately equal to that of titanium, rhodium, manganese and niobium.
This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons.
Depleted uranium ( Uranium is used as a colorant in uranium glass, producing lemon yellow to green colors.
The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99%) and uranium-235 (which has 143 neutrons).
Uranium has the highest atomic weight of the primordially occurring elements.
