Atomic Spectra [9 pts]

Observations of the spectrum of element X show sharp emission lines at the frequencies in Table 2. ( This need not be a complete list of the lines in the spectrum.)

  
Table 2: Observed Spectral Lines for element X


On figure 1, using the least number of energy states possible, sketch a set of energy levels which explain the spectral lines listed in the table, next to each line give the value of its energy (you may place the arbitrary level of zero energy anywhere you wish), and then answer the following question. From your energy diagram, what are the frequencies of other spectral lines (if any) that you might expect to see in the spectrum?

Hint: Note that there are several valid diagrams; you are only required to give one example which produces the observed set of lines.
