Learning outcomes
The course aim to provide the fundamentals of chemistry and chemical-physics useful for the comprehension of materials structure-activity relationship. It also discusses on the materials of specific interest to the Master of Science in Civil Engineering and Architecture.
Course contents
Basics of chemical formulas and chemical reactions
Qualitative and quantitative aspects of chemical formulas and reactions, stoichiometry, principal reaction types.

Radiochemistry
Nuclear stability, radioactive decays, kinetic of radioactive decay, natural radioactive families. Chemical and biological effects of radiations. The environmental radioactivity. Radon.

Basics of chemical bond theory
The hydrogen atom. Electronic configuration of elements and periodic properties. Ionic, covalent, polarized-covalent, coordination and metallic bonds. Molecular geometries. Dipolar moments of molecules. Intermolecular interactions: hydrogen-bond, van der Waals forces and dispersion forces. Ionic and covalent valences of elements of s, p block and first transition row. Oxides, hydrides, anions and cations, salts. Basics of organic chemistry.

States of matter
Gaseous state: ideal gases and real gases. The ideal gas equation. Gaseous mixtures, Dalton’s law, PVT calculations. Solid state: crystalline systems, Bravais’ lattices, compact structures, reference structures for ionic salts. Covalent (diamonds, graphite, silicon, quartz), metallic and molecular crystals. Liquid crystals. Liquid state: surface tension, adhesion and cohesion forces, wettability, vapor tension.

Thermodynamics, kinetics and chemical equilibrium
Thermodynamic state functions. Enthalpy of formation of compounds, heats of reaction, thermodynamic cycles (Hess law), reaction isotherm. The equilibrium in gaseous phase, the equilibrium constant, reaction quotient, the effect of temperature. Basics of chemical kinetics.

Solutions
The measuring units of concentration: molarity, molality, w/w and w/v percent. Liquid-vapor equilibrium, the Raoult’s law. Freezing-point depression, boiling-point elevation, osmotic pressure.
