Electronic Structure of Atoms Problem Set

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

  1. Calculate E for several different transitions, and relate to wavelength.
    1. For Lyman line n=1 to n=2
    2. For Balmer line n=2 to n=4
    3. Ionization of H n=1 to n=&inf;

  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 211, calculate the energy in J mol-1 for gamma rays, X- rays, and Radio Waves.

  4. Based upon the Bohr model of an atom, what would happen for atoms other than Hydrogen? Helium and Lithium for example?

  5. Make a table with the four quantum numbers (n, l, ml, ms) for the valence electrons in the following atoms. a) N, b) O, c) P, d) F1-

  6. Which element could have a ground state valence shell electron in the following orbital.
    1. 3px
    2. 2px, 2py, and 2pz
    3. 3dz2

  7. Write the electron configuration ([Ne] 3s2, 3p4) for the following:
    1. K
    2. Sc
    3. Br
    4. Br1-

  8. Make an energy level diagram that shows the electron energies in the following: a) F b) F1- c) N d) N3- e) Si

  9. Calculate the energy (kJ/mol) and wavelengths responsible for the Balmer series of Hydrogen emission lines.

  10. Explain the following trends in the periodic table. Use data from tables in your book to produce a graph that shows these trends.
    1. Atomic Radius
    2. Ionic Radius
    3. Ionization Energy
    4. Electron Affinity
