This class aims to present to the first-year students the foundations of General Chemistry, starting from the definition of atomic and molecular structure, up to the discussion of simple and more complex theories and models of chemical bonding. Intermolecular interactions will then be used to rationalize the stability and reactivity trends of ions, molecules and condensed systems, such as liquids and solids. A special focus will be given to energetic aspects (thermodynamics and kinetics), experimental laws and interpretative models of equilibria of different types. As an outcome of the first semester lessons, students are expected to dominate the topics of General Chemistry and fruitfully use them as a basis to tackle the topics of following courses.
Course Prerequisites
A necessary knowledge to tackle this course is the ability in reasoning through models and analogies, and in recognizing, within a complex set of cases and phenomenologies, the fundamental trends, by analyzing and simplifying the problems in a critical manner. A good preparation in chemistry, physics and mathematics (at the secondary school level), a high curiosity and the availability of a personal deepening of the different subjects will act as a firm and solid starting point, and an undisputable advantage for understanding most topics.
Teaching Methods
Teaching of this course will be done in the classroom only, during the first semester.
Assessment Methods
The students will be evaluated in a double step exam: a) A simple written test with questions with multiple answers, intended as pre-selection on basic items; b) An oral interview, with attribution of a mark expressed as n/30, to verify the knowledge on all the topics taught in the course.
Contents
The topics presented in this course (72 hours) are present in what is normally included in many University-level textbooks of General Chemistry dedicated to Chemistry students. Therefore, only the main topics illustrated in the classroom are briefly listed hereafter. Atoms and quantum models: from first theories to the contemporary model. Periodic properties. The chemical bond (covalent, ionic, metallic). Shape and size of molecules. (3 FCU). Intermolecular forces. Gases, liquids and solids. Phase transition diagrams. Thermodynamics (enthalpy, entropy and Gibbs free energy) and the chemical equilibrium. (3 FCU) Chemical kinetics. Introduction to radioactivity and nuclear chemistry. Electrochemistry. Oxidation states, redox reactions, Nernst and Faraday laws. Galvanic cells and electrolysis. (3 FCU)
