[60/58]  CHEMISTRY [58/10 - Ord. 2017]  CHIMICA 12 112


The course on Inorganic Chemistry will be mainly focussed on the comprehension of the chemistry of the periodic table through the atomic properties of the chemical elements. Furthermore a deeper insight into the nature of the chemical bonding will be given. Aim of the Laboratory module is to get the students accustomed with laboratory techniques and to introduce them to key aspects of general and Inorganic Chemistry.


The participation requires the pass in General Chemistry and 1st year Laboratory of General Chemistry.
For the final examination the pass in Mathematics I (1st year) is needed as well.

Teaching Methods

Taught class (64 hours) and laboratory sessions (48 hours).
Lessons are held in Italian unless differently required.
Satisfactory attendance in the laboratory throughout the practical course is necessary to pass the module.
Numerical exercizes will be carried out during the semester.

Since a laboratory part is included in the course, attendance is required for both lessons and laboratory sessions. The lessons will preceed the laboratory part.

In order to satisfy specific teaching needs depending on the pandemic outbreak, it will be possible that part of the lessons will be made available through streaming services (Adobe Connect) or recordings will be distributed on-line.
Accordingly, the laboratory attendance might be scheduled for reduced groups of students or replaced by on-line activities.

Verification of learning

The evaluation of the student will occur by means of a written test aimed at verifying the basic knowledge of the topics dealt with in the course, followed by discussion for an in-depth analysis of selected points. The student will have to prove the knowledge peculiar to the course, both from a theoretical and a practical point of view; to be able of personal elaboration; to possess the required skills of communication.
The final ranking is attributed by means of a numerical evaluation expressed in thirtieths. It derives from the estimate (with equal weight) of the written test and the oral discussion, and will also keep into account the work that the student has carried out in the laboratory.
In the laboratory work, the student must show manual skills, ability in discovering interdisciplinar links, and capability to interact with other students in a positive way, fully obeying to security standards and carefully avoiding any risky behavior.
In formulating the final evaluation, the conceptual consistency, the correctness of the logic procedures for solving the proposed exercises, the adequateness of the solutions and a correct expression will be assessed. The former two aspects are mandatory for achieving the pass in the exam: higher ranking will be obtained by students matching all the aspects listed above. In order to get the highest evaluation (30/30 e lode), an excellent knowledge in each aspect dealt with in the course will be needed.

A detailed docimologic table is available on the teaching home page (Una dettagliata Tabella docimologica è disponibile sul sito docente (http://people.unica.it/massimilianoarca/files/2017/03/tabella_docimologica.pdf).

The exams procedures may undergo modifications depending on the evolution of the pandemic outbreak.
