The basic fields of general chemistry are addressed in the course: structure of atoms, periodicity of chemical elements properties, theory of chemical bonding, stereochemistry of molecules, principles of chemical equilibrium. These principles are applied in the description of reactivity and fundamental properties of inorganic substances. The descriptive part of inorganic chemistry is, unlike the conventional treatment (chemistry of elements), approached as a chemistry of inorganic phases. The main families of substances are discussed such as gaseous and liquid molecular compounds, ions in aqueous solutions and their salts, coordination complexes, metals and intermetallic compounds, solid oxides and inorganic polymers, carbides, nitrides and further solid compounds of metals.
