General Inorganic Chemistry
To introduce and rationalize the diversity of inorganic compounds exhibited by the various elements of the Periodic Table. This subject develops along two parts: main group elements (s and p blocks) and transition elements (d block).

The teaching of Inorganic Chemistry (CR) is spread over 26 h of theoretical lessons, complemented by 9 h of exercises and problems solving. The experimental part comprises 24 h of laboratory practice.
1. The final grade (NF) is given by:
NF = 0.25 x P + 0.75 x T
where P is the laboratory grade and T the theoretical grade, both round to the one decimal place.
2. The theoretical grade is obtained through three minitests or through a final exam.
3. The laboratory part is graded by the skills acquired and demonstrated during the lessons and by results obtained on the questionnaires associated to each expriment.
