Question

Hydrogen, deuterium, and singly ionized helium are all examples of one-electron atoms.

The deuterium nucleus has the same charge as the hydrogen nucleus, and almost exactly

twice the mass. The helium nucleus has twice the charge of the hydrogen nucleus, and

almost exactly four times the mass. Make an accurate prediction of the ratios of the

ground state energies of these atoms. (Hint: Remember the variation in the reduced

mass.)
