If a neutral atom has 1 proton, it must have 1 electron. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. Atomic mass units (\(\text{amu}\)) are useful, because, as you can see, the mass of a proton and the mass of a neutron are almost exactly \(1\) in this unit system.
