how many particles are found in the nucleus of a uranium atom? 92 protons and x neutrons; the number of the neutrons is dependent of the isotope atomic mass. Also 92 electrons.
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
In a uranium-238 atom, the number in the isotope name stands for the total number of protons and neutrons in the nucleus. So in this case, uranium-238 has 92 protons (atomic number) and 146 neutrons (238 - 92).
Uranium-230 is a radioactive isotope of uranium with 142 neutrons.
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
There are 92 protons in the nucleus of an atom of Uranium-238.
Uranium 238 has 146 neutrons.
