A hydrogenic atom consists of a single electron orbiting a nucleus with Z protons. (Z = 1 would be hydrogen itself, Z = 2 is ionized helium, Z = 3 is doubly ionized lithium, and so on.) Determine the Bohr energies, E_n (Z) the binding energy E₁ (Z), the Bohr radius a (Z), and the Rydberg constant R (Z) for a hydrogenic atom. (Express your answers as appropriate multiples of hydrogen values.) Where in the electromagnetic spectrum would the Lyman series fall, for Z = 2 and Z = 3? There’s nothing much to calculate here— in the potential (Equation 4.52) e² → Ze², so all you have to do is make the same substitution in all the final results.
