The Interaction of Atoms and Compounds

This book is a continuation of EB-207, EB-300 and EB-354. The book presents the results of calculations of the interaction between atoms and compounds in three-element chemical compounds. A significant part of the compounds considered is intermetallic compounds. Interactions are described by comparing the volumes of the components before and after the interaction. The volumes of atoms and compounds are formed by electrons and are dynamic characteristics. Three-element systems are represented by twenty-one groups. Each group includes a specific element: hydrogen, lithium, beryllium, sodium, magnesium, aluminum, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, galium, germanium and arsenic. The packing coefficient is used as an indicator of interaction. As structural characteristics of substances, it is proposed to describe the space occupied by matter in terms of the concentration of electrons and nucleons. The packing coefficient characterizes the intensity of interaction between atoms and molecules. Comparison of electron concentrations for different substances makes it possible to predict the physical and mechanical properties of the resulting materials. The book can be considered as a reference guide intended for a wide range of physicists, chemists, mineralogists and materials scientists; it can be useful for students of relevant specialties. The presentation is available for high school students.
