This observation is valid not only for uranium but for most stable heavier nuclei (atomic number greater than 30). If enough of these expelled neutrons cause the nuclei of other U-235 atoms to split, releasing further neutrons, a fission 'chain reaction' can be achieved. Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. For the natural isotopes of uranium: Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. How many protons electrons and neutrons does uranium have.
