Learning objectives

Knowledge and understanding: the Chemistry course aims to provide a chemical key for understanding natural phenomena and to introduce the basic concepts for the study of matter in relation to its composition, structure, reactivity, properties. Particular emphasis is given to the study of the structure-property relationships. The theoretical treatment is supplemented with examples and exercises.
Applied knowledge and understanding: the course provides the tools to read the chemical properties of the systems and predict their behavior.
Ability to learn: in addition to the methodological principles, the course aims to provide the fundamentals of the chemical language necessary for the student to read and understand basic and advanced texts on the subject.
Ability to communicate: the student acquires the specific technical language required to communicate with specialists and necessary to properly express even complex concepts in an understandable form.
Making judgments: great care is given so that the student could draw connections not only between the different topics covered in the course but also with concepts acquired in other scientific disciplines in order to be able to form an independent judgment ability based on a knowledge extended to the various aspects of the problem in question.

Prerequisites

No specific chemical knowledge required.

Course unit content

The Chemistry course consists of a first part in which the fundamental concepts necessary for the study of matter in relation to its composition, structure, properties and reactivity are defined using as conceptual tools the modern atomic theory of matter and the periodic properties of the elements. The second part is devoted to the description of the principles determining the formation of strong (ionic and covalent) and weak (van der Waals) interactions in matter. The third part of the course is finally focused on the study of chemical transformations, with particular emphasis on the thermodynamic and kinetic aspect of the processes.

Assessment methods and criteria

The knowledge gained and the ability to understand and apply the topics covered in the course are verified by an oral examination designed to verify the acquired ability to describe chemical systems and describe their transformations with a correct technical-scientific language.
