Sustainable Development Goals
This curricular unit aims to provide students with a comprehensive and integrated approach of the basic theoretical concepts and practical applications of Chemical Bonding. It is intended to present, in a qualitative form, the basic principles of the chemical bonding in several types of substances as well to provide the basic knowledge that will make easier the understanding of some topics that will be developed in other disciplines. At the end students should know and understand the fundamental concepts and principles of chemical bonding and to predict atomic and molecular properties, Lewis structures, electronic structure, molecular geometry, and molecular properties (e.g., bond order and distance, paramagnetism, acid/base behavior, nucleofilicity and electrofilicity, ionization energy, electron affinity, conductor, semi-conductor or insulating properties) using Valence Bond Theory and Molecular Orbital Theory.
1. Atomic structure and atomic molecules Atomic orbitals
2. Chemical bonding in molecules (Valence Bond and Molecular Orbital Theories. Study of diatomic and poliatomic molecules. Prevision of geometries. Dipolar moment, polarity of molecules).
3. Intermolecular forces Bulk properties (Covalent crystals, ionic crystals, metals, and semiconductors).
4. Introduction to chemical bonding in coordination compounds.
Teaching and learning is based on the individual work of the student, supported by the recommended reading and by the notes taken by the students during the contact hours and during individual research by the student himself, whenever possible, in the facilities equipment of the University. The classes are not purely expository but accompanied by practical activities and interspersed with classes for the orientation of the learning process.
The assessment will be based in two components, a theoretical component (60%) and a project component (40%). The approval in the theoretical component can be achieved by one final exam or by partial exams. The approval in the project component is obtained by the elaboration of written reports and by oral presentations and discussion of some proposed activities.
