65931 - Inorganic and General Chemistry

Learning outcomes

The scope of the course is to provide a fundamental knowledge of chemistry, allowing the student to understand and take up the following specialised topics in chemistry. In particular, the student will be able to critically analyse the following topics: the composition of matter; the relationships between the macroscopic properties of matter and its atomic and molecular composition; the reactivity of substances.

Teaching methods

The lectures will involve the use of presentations through a beamer driven by a PC. Multimedial material will be presented, such as slides, movies, animations and three-dimensional visualization of atoms, molecules and materials. Problem solving sessions will be carried out in order for the student to gain acquaintance with the numeric treatment of chemical problems.

Assessment methods

The final examination comprises a test made of questions and numeric problems, as well as a colloquium. Access to the colloquium is not prevented if the test is failed, but the test outcome will be considered to determine the final grade. No partial tests will be carried out through the teaching period.

Teaching tools

The multimedial material utilized during the lectures will be made available for download from the teacher's web site.
