WebDec 26, 2024 · Uranium Isotopes . There are two naturally-occurring isotopes of uranium. Natural uranium consists mostly of isotope U-238, with 92 protons and 146 neutrons (92+146=238) contained in each atom. Mixed with this is a 0.6% accumulation of U-235, with only 143 neutrons per atom. WebUranium-235 is an isotope of uranium that differs from the element's other common isotope, uranium-238, by its ability to cause a rapidly expanding fission chain reaction, i.e., it is fissile. It is the only fissile isotope found in any economic quantity in nature. It was discovered in 1935 by Arthur Jeffrey Dempster .

Uranium-235 ( U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur … WebAs uranium-235 is so rare in nature, uranium has to go through a process called enrichment so that enough uranium-235 is present to use as a fuel for nuclear energy. Uranium-238 can be converted to a fissile substance called plutonium-239, in a nuclear reactor, and then used for fission. Another isotope of uranium that is fissile is uranium-233.
