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.
For now, the new substance will be principally known as element 118 for the number of protons in its nucleus, more than in any other element occurring naturally or produced in the laboratory. Hydrogen, the lightest element, has one proton in its nucleus, and uranium, the heaviest naturally occurring element, has 92.
