The argument given in part 2 (that the strength of nuclear forces compared to electric forces make nuclei very heavy relative to the energies that would rip their chemistry apart) does not make a lot of sense in the context of the fact that binding energy reduces the mass of bound states. For example, 56Fe is lighter than 26 protons and 30 neutrons. The ratio of the Hydrogen atom's ground state electron binding energy to the electron's mass-energy is one half the fine structure constant squared. That implies the nuclear forces don't have much to do with it - electromagnetism is simply, and dimensionlessly (i.e. independently of any arbitrary units or scales), a weak force.
