Prerequisites
Basic knowledge in mathematics, in particular differential and integral calculations.
Learning outcomes
The course aim to provide the fundamentals of chemistry and chemical-physics useful for the comprehension of materials structure-activity relationship. In particular, students will be able to predict the products of inorganic reactions starting from reagents. Moreover, thermodynamic will be used to predict the heat of reaction and the spontaneity. In this way the student should be able to predict if the reaction occurs or not.
Course contents
Basics of chemical formulas and chemical reactions
Qualitative and quantitative aspects of chemical formulas and reactions, stoichiometry, principal reaction types

Radiochemistry
