This course illustrates the basic principles of chemistry which are useful for the study of cultural heritage.
The main target of the course is giving the students strong chemical foundations, stressing the general principles of basic subjects such as atomic and molecular structure, nomenclature, isomerism, physical and chemical properties, reactivity. On these foundations it will be based a unitary, reasonably detailed and complete vision of the various features of the chemicals of greater specific interest, and of their use in preservation, consolidation and restoration of cultural heritage also through laboratory training
To enable students to understand structures and properties of the chemicals they are going to use in their future work.
To show that chemistry is a rational science, that all the subjects are connected together, so that the course is a unique reasoning developing from the first to the last lesson
Frontal lessons with slide projections and frequent interactions with the students
The Fundamental Laws of Nature. Molecular stability as determined by attractive and repulsuve intramolecular forces.
From atomic structure to the Periodic Table, to the various kinds of chemical bonds, to valence and to the various kinds of formulas. The 3D-structure of molecules and their simple rationale (VSEPR). Molecular models. Continuous and complete rotation around chemical bonds in open chains. Conformations. Possible rigid or semi-rigid sub-structures (double bonds, cycles) and possible cis/trans (Z/E) configurations. Symmetry planes. Chirality. Possible R/S confiurations. Molecules with one or more chirality centers. Constitutional or structural isomerism. Stereoisomerism: enantiomerism and diastereoisomerism.
Probabilistic character of our knowledge about the position of an electron in an atom. Atomic and molecular orbitals. The hybridation method. The resonance method. Electron delocalization and molecular stability. Resonance energy
Inorganic compounds.

CHEMISTRY FOR CULTURAL HERITAGE MODULE I
After following the two modules of the course, students have to pass a unique exam, which will be an oral discussion of the various subjects of the both the modules.
It is important that the students exhibits a real understanding of the matter, not only a by-heart study.
