1. On a piece of graph paper, draw to scale a diagram depicting the energy values for the first 6 energy levels of hydrogen. Write the energy values in ev. Show the energy level transitions for the Lyman (nr = 1), Balmer (nr = 2), and Paschen (nr = 3) series of spectral lines. Determine which series corresponds to visible, UV, and infrared light. Support your conclusions with calculations. Determine the wavelengths of photons given off for the 3'd line in the Lyman series, the 2"d line in the Balmer series, and the 1" line in the Paschen series. ( /10) 2. If the line with the longest wavelength in the Paschen series for atomic hydrogen is counted as the first line, what is the wavelength of the third line? ( /2) 3. Using a written description and diagrams, summarize the concepts involved with the Bohr model of the atom. Mention where the Bohr model fails. and how the subsequent quantum model of the atom corrected these inaccuracies. ( /4)
