Learning outcomes
At the end of the course, students have a good knowledge of properties of both chemical element and compounds in relation to their electronic structure and to the nature of chemical bond. In particular, students will be able to evaluate behavior of organic molecules and biological materials.
Course contents
Atomic structure of matter : atoms, fundamental particles, atomic number, isotopes, atomic mass, mole and molar mass. Nomenclature of compounds.
Electronic structure of atoms and periodicity of atomic properties: the wave nature of matter, wave mechanics, atomic orbitals, quantum numbers, electron configurations of the elements and periodic properties.
Chemical bonds : ionic bonds and structure of ionic crystals. Covalent bond: hybrid orbitals and molecular structure, molecular orbital theory. Covalent crystals. Polarity of molecules. Metallic bond: band theory. Weak interactions.
Stoichiometry, chemical reactions and redox.
States of matter: gases, ideal gas law, mixture of gases and real gases. Liquid state: solutions and measures of concentration. Exercises. Solids: kinds of crystals.
Thermochemistry: Hess's Law of heat. Standard reactions enthalpies, enthalpies of formation and combustion.
