1. Predict the electron configuration for the following: a) Sc; b) Sc+; c) Sc3+; d) Sc3+. Find all of the Russell-Saunders term symbols for each of these ions.
2. Draw the lowest energy Lewis dot structure for each of the following, indicate the molecular geometry including an estimate of all bond angles, and give the point group: a) AsF6–; b) XeO3; c) SO3; d) ClO3–.
3. Find the irreducible representations for the sigma bonds and lone pairs in PI3. What hybrid must be used?
4. Predict the relative solubility of NaCl in cyclohexanol, cyclohexane, and benzene. Indicate the weak interactions that would promote the solubility. Would your prediction change for CsCl? Why or why not?
