Properties of Uranium
Uranium is a radioactive element that occurs naturally in varying but small amounts in soil, rocks, water, plants, animals and all human beings. It is the heaviest naturally occurring element, with an atomic number of 92. In its pure form, uranium is a silver-colored heavy metal that is nearly twice as dense as lead. In nature, uranium atoms exist as several isotopes, which are identified by the total number of protons and neutrons in the nucleus: uranium-238, uranium-235, and uranium-234. (Isotopes of an element have the same number of protons in the nucleus, but a different number of neutrons.) In a typical sample of natural uranium, most of the weight (99.27%) consists of atoms of uranium-238. About 0.72% of the weight consists of atoms of uranium-235, and a very small amount (0.0055% by weight) is uranium-234.

Uranium Oxides - U3O8 and UO2
The most common forms of uranium oxide are U3O8 and UO2. Both oxide forms are solids that have low solubility in water and are relatively stable over a wide range of environmental conditions. Triuranium octaoxide (U3O8) is the most stable form of uranium and is the form most commonly found in nature. Uranium dioxide (UO2) is the form in which uranium is most commonly used as a nuclear reactor fuel. At ambient temperatures, UO2 will gradually convert to U3O8. Because of their stability, uranium oxides are generally considered the preferred chemical form for storage or disposal.

Commonly known as U92, to a lot of people.
