The proton and neutron are found inside the nucleus at the centre of an atom. The nucleus is smaller than the size of an atom as a whole, and the electrons are arranged in shells … WebSince electrons have so much less mass than protons and neutrons, almost all of the mass of an atom comes from the protons and neutrons. The amount of mass that an atom gets from its electrons is so tiny that for most purposes we can just ignore it. In other words, the electron’s mass is negligible (which means so small that it can be ignored ...
