1) First Ionization Energies across a period, e.g., period 2. explain in detail why there are anomalies for Boron and Oxygen.
2) Explain the subshell hybridization of elements such as copper or chromium
3) Understand the Bohr and quantum mechanical atomic models
4) Predict and Explain why a particular ion forms, e.g., Ti2+
5) The general orbital filling progressions such as why would a 3d fill after a 4s?
6) In ion formation, why would a 4s electron leave before a 3d electron?
