WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the … WebA proton is one of the subatomic particles that make up matter. In the universe, protons are abundant, making up about half of all visible matter.It has a positive electric charge (+1e) and a rest mass equal to 1.67262 × 10 −27 kg (938.272 MeV/c 2)— marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron.
