In nature, uranium is found as uranium 238 (99.2739 99.2752 ), uranium 235 (0.7198 0.7202 ), and a very small amount of uranium 234 (0.0050 0.0059 ).

The most common isotopes of uranium are uranium 238 (which has 146 neutrons and accounts for almost 99.3 of the uranium found in nature) and uranium 235 (which has 143 neutrons, accounting for 0.7 of the element found naturally).
