Transition metals and the crystal field model (1)
Chemistry: Transition metals and the crystal field model. Strong-field case and weak-field case; low-spin case and high-spin case; paramagnetism and diamagnetism; spectrochemical series; colors of complex ions. The localized electron model of bonding in complex ions, also known as the valence bond model This is a recording of a tutoring session, posted with the students' permission.
