2010 Chemistry 2353 Assignment 2 1. (3 pts) Using Slater’s rules, determine the effective nuclear charge for a 2p electron in O and O 2-. Discuss the relative sizes of the atomic/ionic radii based on your result. 2. (5 pts) Using Slater’s rules, calculate Z eff for the outermost electron in Al, Al + , Al 2+ and Al 3+ . Discuss your results relative to the expected ionization energies for these species. Be specific. 3. (2 pts) Which of the following pairs will be smaller? Explain your reasoning. Br- or Rb + 4. (4 pts) Rank the following atoms in order of increasing ionization energy. Explain the reasoning behind your ranking. Si, P, and S 5.
