  • Objectives

                                 


    Chemistry is considered an integral part of the history of science and the contemporary world. In general, general chemistry describes the reactivity of elements and their compounds, while providing a broad overview of the principles on which chemistry is based, and is the basis of initial scientific training for chemists. This course contains theoretical developments and uses mathematical tools to understand certain notions of structural chemistry.
