Neutrons 143
Protons 92
92+143=235
For other isotopes: number of neutrons = Atomic Mass (or mass number) - number of protons

Uranium-235 has 92 protons and 92 electrons. This is because the number of protons in an atom is equal to its atomic number, which is 92 for uranium. The number of electrons is also equal to the number of protons in a neutral atom.
Uranium has 92 protons and 92 electrons as its atomic number is 92. In U-235, there are 143 neutrons (235 - 92 = 143)
Uranium has 92 protons, and an uncharged atom will have 92 electrons. The number of neutrons is 235-92 = 143 neutrons.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
There are 92 protons in the uranium isotope 235U. The atomic number of an element, represented by the subscript, tells you the number of protons in the nucleus.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).
The atomic number of uranium is 92. Uranium-235 has 143 neutrons.
The mass number of uranium-235 is 235, which is the total number of protons and neutrons in the nucleus of an atom of uranium-235.
