The most common isotope of uranium is uranium-238 with 146 neutrons.
And what is the question?
Uranium has many isotopes and each isotope has a different number of neutrons (N). N = atomic weight of the isotope - atomic number of uranium (A=92) The number of neutrons of the isotope 92U238 is 238-92=146 and the number of neutrons of the isotope 92U235 is 235-92=143.
92 protons 92 electrons, 125 to 150 neutrons depending on the isotope (natural or artificial). For the natural isotopes of uranium: Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. Uranium 235 has: 92 protons, 92 electrons and 143 neutrons. Uranium 234 has: 92 protons, 92 electrons and 142 neutrons.
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
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.
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Uranium has 92 protons and electrons; the number of neutrons is different for each isotope: number of neutrons = atomic mass of an isotope - atomic number of uranium (92)
And what is the question?
Each isotope of an element has a specific number of neutrons (number of neutrons = atomic weight - atomic number).
Number of neutrons in an atomic nucleus = Atomic mass of an isotope - Number of protons in the nucleus For uranium the number of protons is 92; each isotope has of course a different mass.
You can't have that combination. Such an atom wouldn't be stable - not even for a tiny fraction of a second.The atomic mass is the sum of the atomic number (i.e., the number of protons), and the number of neutrons.
All the isotopes of uranium contain 92 protons; the number of neutrons is variable for each isotope: Number of neutrons = Atomic weight of the given isotope - 92

Uranium 235 has: 92 protons, 92 electrons and 143 neutrons. Uranium 234 has: 92 protons, 92 electrons and 142 neutrons.
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
All the isotopes of uranium have 92 protons and electrons.The number of neutrons is Mass number- Atomic number.
