Uranium is extracted as U3O8, an oxide known as yellowcake.
Uranium may also be present in water as the UO22+ uranyl cation.
Most uranium is U-238, which has a half-life of 4.5 billion years.
---------
Uranium has about 200 minerals. See for some examples: http://www.webmineral.com/chem/Chem-U.shtml
The yellowcake is the ammonium diuranate (NH4)2 U2O7 (yellow colour); U3O8 (triuraniumoctaoxyde) is black.
Uranium is a chemical element, natural, radioactive, solid, metal.

What is uranium 235 when added to natural uranium?
Uranium-235 is not added to natural uranium, it is extracted from natural uranium by a process called enrichment.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What is the ratio of uranium isotopes U-238 to U-235 in natural uranium?
Concentration of 238U in natural uranium: 99,2742 % Concentration of 235U in natural uranium: 0,7204 % The ratio 238U/235U is 137,804.
What does Uranium do to your skin?
The effect of uranium on skin depends from: chemical form (fluoride, metal, nitrate, etc.), physical form (solid, liquid-solution, gas), quantity, time of contact, particles dimensions, etc. Uranium metal (natural isotopic composition) in bulk form is not so dangerous.
Is uranium synthetic?
No, uranium is a natural chemical element.
What is uranium 235 when added to natural uranium?
Uranium-235 is not added to natural uranium, it is extracted from natural uranium by a process called enrichment.
How the plutonium is form by natural uranium?
plutonium can only form from uranium in a nuclear reactor. since the last natural reactors on earth shut down about 3 billion years ago (oklo) it can't happen naturally now.
What is uranium - 235 when added to natural uranium?
Natural uranium has approx. 0,7 % 235U; uranium with more than 0,7 % 235U is an enriched uranium.
Is uranium a natural element?
Yes, uranium is a natural but radioactive element.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What is the ratio of uranium isotopes U-238 to U-235 in natural uranium?

Is uranium a base?
Uranium is a natural, radioactive metal.
Is uranium synthetic?
No, uranium is a natural chemical element.
How do humans use uranium in the natural environment?
Uranium is a possible polluting agent of the natural environment.
What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
Is depleted uranium 40 percent more radioactive than natural uranium?
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
