Atomic Structure Problem Set

This problem set was developed by S.E. Van Bramer for Chemistry 145 at Widener University.


  1. Calculate [delta]E, frequency, and wavelength for the following transitions in the hydrogen spectrum.
    1. Lyman [alpha] line n=1 to n=2
    2. Balmer line n=2 to n=4
    3. Ionization of H n=1 to n=[infinity]

  2. Compare the three different types of radioactive particles. What are the differences between these particles?

  3. Based upon the wavelength information given in figure 7.3, calculate the typical energy in J mol-1 for gamma rays, X- rays, and Radio Waves.

  4. I just bought a new truck, calculate the DeBroglie wavelength if it is traveling down the highway at 65 miles per hour (the truck has a weight of 3675 pounds). Calculate the DeBroglie wavelength for an electron (mass 9.10953 x 10-31 kg) traveling at a speed of 100,000 miles per hour. Compare the wavelengths and their relative significance.

  5. Sketch the shape of the s, px, py, and pz orbitals.
