The Interaction of Atoms and Molecules

Grigorii Seguru, Valery Fertikov

Abstract:
This book is a continuation of EB-207 and EB-300 books. The book presents the results of calculations of the interaction between atoms and molecules in three-element chemical compounds. Interactions are described by comparing the volumes of the components before and after the interaction. The volumes of atoms and molecules are formed by electrons and are dynamic characteristics. Calculations reflect interactions in three-element systems Three-element systems are represented by six groups. Each group includes an element: 1-boron, 2-carbon, 3- nitrogen, 4-silicon, 5-phosphorus and 6-sulfur. 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 electron concentration and nucleon concentration. 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 book 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.
