Morphological classification of chemical structural units

A new classification of chemical structural units (csu), based on their ele mental chemical transformations, is presented. It origins from a new unifor m numerical definitions of acids, bases, oxidators and reductors and a new numerical approach to the periodic chart of elements. According to these as sumptions csu and their combinations are distributed in a multi-dimensional classification space. Much attention has been paid to prove experimentally that the virtual classification steps present the real steps of chemical r eactions of csu. Thermal decomposition stages as well as syntheses of salts in solid state were investigated. Applications of classification presented in research and didactics have been discussed.
