Nucleons are less massive when in the nucleus than when they are separated,atoms are less massive than the particles which make them up,these differences being explained in terms of binding energy.Does this mean,for example, that the electron and proton both lose mass when they come together to form the hydrogen atom?If so I thought the belief was that particles such as electrons have a mass which is invariant.What am I missing?
