Description
At the end of the course, students should be able to:
State the main physico-chemical properties of transition elements and introduce crystal field theory
On the basis of solid-state chemist reasoning, predict the stability of an ion in a given site or structure (by performing crystal field stabilization energy calculations, for example, or by considering ionic radius evolutions)
State the physico-chemical processes that explain the color of transition element compounds. Know how to use Tanabe Sugano diagrams.
Name the characterization techniques to be used to determine the structure and chemical formula of a material, and establish a realistic and coherent chemical formula using the results obtained. In particular, determine the degrees of oxidation and electronic configurations of ions on the basis of magnetic measurements.
Make links between the structure/chemical formula (degrees of oxidation of ions, configurations, stoichiometry) and certain properties (electrical conduction, color) of materials.
