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.
