Best Answer: U-238 is by far the most common isotope of Uranium found naturally, 99.284%. It has 238 nucleons, 92 of which are protons. The remaining 146 are neutrons. U-235, which accounts for 0.711% of all Uranium found naturally, is the useful one for fission reactors (and bombs), has 235 - 92 = 143 neutrons. U-234 is also found in extremely small quantities, 0.0058%, and has 142 neutrons.
The element, uranium, has an atomic number of 92. That means that, assuming it's electrically neutral, it has 92 protons and 92 electrons. Since we know that this particular i â¦ sotope of uranium has a combined total of 238 protons and neutrons, the total number of neutrons in 238U is 238 - 92 = 146. Uranium 238 has: 92 protons, 92 electrons and 146 neutrons.
