Neutrons are slightly more massive than protons. If the mass of a neutron were smaller than its actual value, yet still more massive than a proton, a nucleus with a very high atomic number would mos
A stable nucleus contains many protons very close to each other, all positively charged. Why do the protons not fly apart due to mutual Coulomb repulsion?
