A scientist uses atomic emission spectroscopy to analyze an unknown sample. A series of lines in the far UV are observed at the following wavelengths (all in nanometer units):

The scientist notes a similarity to the hydrogen atom spectrum. Assume the first set are transitions that end in the n = 1 state, the second end in the n = 2 state, and so on. Calculate R (in J) from the data. Calculate the number of positive charges on the species and identify the species.
