Web10 apr. 2024 · Isotopes of Uranium. The most common isotopes of uranium are uranium-238 and uranium-235. Uranium-238: It is the most abundant isotope of uranium, accounting for over 99% of natural uranium. It has 92 protons and 146 neutrons in its nucleus. It is not fissile, which means it cannot sustain a nuclear chain reaction. WebThe most common isotope of uranium is U-238, but the form used in nuclear bombs and nuclear power plants is U-235. Given that uranium has atomic number 92, how many neutrons are in each of these two isotopes?
