The challenge for commercial … NettetUranium-235 ( 235U 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 is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes, making them useful for dati…

NettetAs 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 …
