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 … WebThe relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass. The mass of electrons is very small compared to protons and neutrons.
