| Περίληψη: | Definition, main transition elements of the d-block and f-block (lanthanides, actinides). Lanthanides (electronic structure, origin, properties, lanthanide contraction, uses). Actinides. Physical and chemical properties of the transition elements (existence of many oxidation states, comparison of the radii and the melting points of the transition metals from the different periods). Chromium, molybdenum, tungsten (production of pure metals from their minerals, physical and chemical properties, uses of the transition elements and their compounds). Magnetism and transition elements (basic principles of magnetism, diamagnetism, paramagnetism, determination of the magnetic susceptibility, origin of the magnetic moments, ferromagnetism and antiferromagnetism). Demonstration of the lab exercise: “Synthesis of nano-powders of the type La1-xSrxMnO3-δ”
