| Abstract: | Development of the orbital electronegativity concept since, 1934 is considered. It is shown that the concept is well substantiated from the quantum chemical viewpoint and is used in such fields of chemistry and crystal chemistry as the Lewis acid-base theory, the reactivity theory, etc. Its application is based on the electronegativity balance principle, which includes not only intraatomic effects but also different interatomic interaction contributions. The concept became a natural tool in modern methods for predicting and modeling the structure and properties of molecules and crystals. M. V. Lomonosov Moscow State University.
