* Protons: The atomic number of uranium is 92, meaning every uranium atom has 92 protons.
* Neutrons: The mass number of Uranium-235 is 235. To find the number of neutrons, subtract the number of protons: 235 - 92 = 143 neutrons.
* Electrons: In a neutral atom, the number of electrons equals the number of protons. Therefore, a Uranium-235 atom has 92 electrons.
Total Subatomic Particles: 92 protons + 143 neutrons + 92 electrons = 327 subatomic particles
