Uranium-238 is the most commonly existing isotope of uranium. It is the most stable isotope with half-life roughly equal to the age of earth. Other two major isotopes of uranium include uranium-235 (which is 0.71% of naturally occurring uranium) and uranium-234 (0.0054% of naturally occurring uranium).

Uranium occurs in the earths crust as an ore and is not free elementally. Whilst uranium is dangerous it emits alpha particles which cannot penetrate skin, however it is still highly toxic and easily ignites as a powder. It is a solid metal at room temperature and it has a melting point of 1132°c and a boiling point of 4131°c.

Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Uranium-235 is the only naturally occurring fissionable fuel (a fuel that can sustain a chain reaction). Uranium fuel used in nuclear reactors is enriched with uranium-235. The chain reaction is carefully controlled using neutron-absorbing materials.
