Assessment Methods

Verification of learning:

The final evaluaion consists in a written and oral exam. The written exam will evaluate the ability to solve practical problems and define molecular geometries and properties. The oral examination will verify the overall knowledge of the arguments of the course and the skills to apply and connect knowledge in the field.

The course also includes Interim assessment tests, which may exonerate the student from the final written exam and allow direct access to the oral exam.

Teaching period

Second semester

Objectives

To give comprehensive basic information of the stereochemistry and reactivity of the compounds of main group elements with references to applicative aspects. To rationalize the diversity of the chemical phenomena with the help of the periodic table and physical chemistry.
Strengthen the skills necessary in an inorganic chemistry laboratory.

Contents

General contents

Laboratory experiences.
The experiments were chosen to exemplify what was discussed in Inorganic Chemistry I, and consist of the synthesis and characterization of compounds of the elements of the main groups, the separation of products, and experiences of their reactivity

Conventional

Teaching Methods

Lectures with slides and practical laboratory exercitations.

Contacts/More Information

Attendance of lessons and lab execitations is compulsory.
At the end of each laboratory experience, students will have to send a brief report by e-mail.
If required, the teacher is available to give explanations in english. An English text of main group chemistry is also included in the list of the recommended texts.
During the semester, learning will be assessed by at least two written tests comprising a series of multiple-choice questions and some open questions which require brief but exhaustive answers
