For example, how many protons does the element with a mass number 35 if it has 18 neutrons? Hopefully, after reading this article you will know the details about this topic. The number of protons determines an elements atomic number (Z) and distinguishes one element from another. Lets keep using oxygen as our example. For example, carbons atomic number (Z) is 6 because it has 6 protons. Nucleus: The central part of an atom that contains the protons and neutrons. Having 35 electrons means it also has 35 protons, and if we subtract this from the atomic mass, we will know how many neutrons it has. Electrons: Negatively charged subatomic particles located in orbitals surrounding the nucleus. Protons Neutrons Electrons Boron B 11 5 5 6 5 Sodium 24 11 Y 89 39 Copper 29 35 Tc 98 43 Pb 207 Thallium 204 81 .
