This worksheet was developed for a second-year descriptive inorganic chemistry class. Students have been introduced to periodic trends, electron configurations for transition metals, crystal structure and site symmetry, and are beginning a discussion of crystal field theory. They should also have been exposed to the spectrochemical series and ligand field splitting. This worksheet is used as a way of integrating knowledge across several chapters and several weeks of the semester, in preparation for a more advanced discussion of color in pigments and gemstones. After a brief introduction, students will work in small groups during class time to answer the worksheet questions. The questions follow closely with content in the textbook (Descriptive Inorganic Chemistry Raynor-Canham, Overton 6^th ed.), and so should be mostly a review and opportunity for students to apply their understanding to a concrete problem.
