This is an in class exercise that I use to introduce structure and magnetism to a junior/senior level course on bioinorganic chemistry. The class is cross-listed between Chemistry and Biochemistry. All of the students have had general chemistry and organic (with some exposure to MO Theory). Many of the students have also had the sophomore-level inorganic course, which delves extensively into MO theory, and some of the the students have also had the senior-level course on transition metal chemistry which looks deeply at d-orbital splitting. Because of the different levels of preparedness, the questions that I discuss in class as a result of the worksheet vary.
• A student should be able to identify the number of d-electrons for a given oxidation state for a given metal.
• A student should be able to fill the orbital energy diagram, applying the Aufbau Principle, Hund's Rule, and the Pauli Exclusion Principle.
• A student should be able to distinguish between a magnetic and a paramagnetic configuration.
While this LO was written with a bioinorganic course in mind, it could easily be used in an inorganic class as an example of the usefulness of magnetism to applied problems.
