Source(s): Chart at bottom: Also 2010-04-05 · You can find that on a periodic table by looking up uranium. To find the neutrons subtract the protons from the 234, 235, and 238. So, for Uranium-234, there are 234-92=142 neutrons. Do the same 2019-11-28 · The radioactive isotope 238u decays in a series of nuclear reactions that includes another uranium isotope, 234u, and three lead isotopes, 214pb, 210pb, and 206pb. how many neutrons, protons, and electrons are in each of these five isotopes The photofission of 232Th, 234U and 238U at excitation energies in the barrier region has been studied.

92p 142n. electrons: same number as protons, except in ions. Uranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. Uranium 234, which alone constitutes only 0.0054% (54 parts per million) of natural uranium is the last naturally-occurring isotope of uranium.

226Ra\\\/230Th method is used to date continental Naturally occurring uranium metal has 3 major isotopes, 235U (0.71 percent), 238U (99.28 percent abundance), and 234U (0.0054 percent). The isotopes of uranium are radioactive. 235U is the only naturally occurring fissile isotope while 238U is the most stable isotope of uranium metal which makes up to 99% of the naturally occurring uranium. 233U is another fissile isotope that can be produced However, the gas diffusion or gas centrifuge processes for $\ce{^235U}$ enrichment do not only lead to an increase in the $\ce{^235U}$ concentration in the fuel, but also to a more than proportional increase in the $\ce{^234U}$ concentration.
