Draw an energy-level diagram, similar toFigure 38.21, for the He⁺ion. On your diagram:

a. Show the first five energy levels. Label each with the values of n and E_n.
b. Show the ionization limit.
c. Show all possible emission transitions from the n = 4 energy level.
d. Calculate the wavelengths (in nm) for each of the transitions in part c and show them alongside the appropriate arrow.
