Overall objectives:

1 - This course aims to provide the students with the scientific basis of Inorganic and Bioinorganic Chemistry to understand the role of metals in biological systems.
2 - At the same time, the student is expected to understand the importance of this knowledge for the development of society, namely in the biomedical field.
3 - The skills/competences to be developed by the student include the ability to study autonomously, critical thinking, teamwork, the search/use of scientific information, and the communication of science in written and oral form.

Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
This curricular unit has 64 hours of contact between the teacher and the students, which are divided into 40 hours for theory, and 24h for lab classes. The lectures will be given with the help of audiovisual media and a blackboard, with the teacher maintaining a permanent dialogue with the students (asking and answering questions). The material used for lectures and exercises will be made available to students through the course web page. Evaluation: Theory evaluation (70%): Two tests (minimum score in each test: 9.5) Laboratory evaluation (30%): Pre-report + questions (30%); Oral presentation (15%); Performance (30%); Final Report - treatment of results (25%). The final approval is dependent on achieving a minimum score of 9.5 in each evaluation component (theory and laboratory).
