Top 24 interesting facts about Uranium

  • Uranium was discovered in 1789 by Martin Klaproth. Its name derives from the name of the planet Uranus.
  • Uranium's melting point is at 1132.0 C (1405.15 K, 2069.6 F) and its boiling point is at 3818.0 C (4091.15 K, 6904.4 F).
  • Uranium has a silvery-white color.
  • Uranium is malleable and ductile.
  • Uranium is strongly electropositive and poor electrical conductor.
  • Uranium is weakly radioactive.
  • Uranium has the second highest atomic weight among elements (it is only lighter than plutonium).
  • Uranium forms a coat of uranium oxide when exposed to air.
  • Uranium is the 51st more abundant element on Earth.
  • Uranium is mainly extracted from uraninite ore.
  • Uranium has three naturally occurring isotopes.
  • Uranium-238 is the most abundant isotope (more than 99%).
