Learning of the fundamental concepts of inorganic chemistry: structure of matter, systematics and nomenclature of basic compounds, mass of compounds and chemical transformations, acids and bases, solutions and concentrations, electrochemistry, stoichiometry.
General introductory concepts Classification of matter - Element - Compound - Atom and molecule - Atomic mass - Scale of atomic masses - Determination of atomic masses - Isotopes - Molecular and molar mass - Avogadro's constant - Mole.
Chemical systematics Oxidation number - Minimum formula, molecular formula and their determination - Formulas and nomenclature of the main classes of inorganic compounds.
Chemical reactions General and classification of chemical reactions - Quantitative significance of chemical reactions - Stoichiometric calculations - Non redox, redox and dismutation reactions - Reactions in complete and ionic form.
Structure of the atom Fundamental constituents of the atom - Quantum numbers - Atomic orbitals - Pauli exclusion principle - Hund principle - Periodic system and electronic configuration - Periodic law and periodicity of the properties of the elements (atomic and ionic rays, ionization energy, electron affinity, electronegativity, metallic character)
Chemical bond Ionic bond - Covalent bond - Dative bond - Geometry of inorganic molecules, VSEPR theory - Hydrogen bond, dipolar interactions, van der Waals forces
Chemical equilibrium General - Homogeneous and heterogeneous equilibria - equilibrium constant - Displacement of equilibrium: Le Chatelier's principle, effect of temperature, pressure and variation of concentrations on equilibrium.
Solutions Types of solutions and solubilization mechanisms - Concentration of solutions (% by mass, mole fraction, molality,% by volume, molarity and normality) - Raoult's law - Diluted solutions of non-volatile solutes - Variations in vapor pressure, temperature boiling and solidification of the solvent - Osmotic pressure - Electrolyte solutions: degree of dissociation - Solubility of gases in liquids.

Final oral exam.
The oral exam is always conducted by two tenured teachers, lasts at least 30 minutes and focuses on all the topics covered in class.
With the methods described above, given that at least one of the two teachers has many years of exams experience in the discipline, the commission is able to verify with high accuracy the achievement of the educational objectives of the teaching. When these are not reached, the student is invited to deepen the study and to make use of further explanations by the lecturer. The CCS guarantees the correspondence between the topics of the exam and those actually carried out during the course. To this end, the teacher in charge makes the detailed program public at the beginning of the lessons (on a site called the web room reserved for teachers and students of the University). Furthermore, at the end of the course, the register of lessons is published on a site reserved for CCS members and student representatives. In this way the students themselves can verify compliance with this rule.
