The aim of the course is to acquire the main concepts of General Chemistry and some notions of Inorganic Chemistry. In particular: - models and general concepts for the explanation and prediction of some physics and chemistry properties of systems of increasing complexity: single atoms, ions, molecules, pure substances, macroscopic systems of one or more components; - concepts and methods to qualitatively and quantitatively predict the variations of the intensive and extensive properties of chemical systems in evolution. The course is integrated with a series of introductory laboratory experiments.
