Apply the techniques of this Section to the H β and Li + ions (each has two electrons, like helium, but nuclear charges and , respectively). Find the effective (partially shielded) nuclear charge, and determine the best upper bound on , for each case. Comment: In the case of H β you should find that eV, which would appear to indicate that there is no bound state at all, since it would be energetically favorable for one electron to fly off, leaving behind a neutral hydrogen atom. This is not entirely surprising, since the electrons are less strongly attracted to the nucleus than they are in helium, and the electron repulsion tends to break the atom apart. However, it turns out to be incorrect. With a more sophi
