Quiz #3: Atomic Levels (Topic 3) February 20, 2008 Name: ____SOLUTIONS__________ Problem 1 Carefully draw an energy-level diagram for a one-electron ion Be 3+ . Draw the levels n = 1, 2, 3, and and write an expression for the energy levels. Calculate the energy of the electron in these states. Use arrows to indicate the following transitions on the diagram and find the photon energies for: a) longest wavelength transition in the Lyman series, and b) highest energy transition of the Paschen series. 2 2 0 1 22 2 23 2 21 3 13.6 eV 4 = 217.6 eV, 1 13.6 eV 13.6 eV 13.6 eV 4 = 54.4 eV, 4 = 24.2 eV, 4 = 0 ) 54.4 ( 217.6) 163.2
