SOME FUNDAMENTAL PROBLEMS IN CRYSTAL CHEMISTRY AND THEIR USE IN MINERALOGY,
Abstract
Analysis of the three most important problems in crystal chemistry shows that the original representations which are based on a formal-geometric theory of the formation of crystals are insufficient for explaining facts established in the last ten years of the development of this science. An attempt was made to develop more correct representations of the nature of crystal material, based on the energy properties and structure of the electron shells of the atoms. The effect was stressed of their fundamental properties on the chemical bonds between them, on which depend the effective radii and the appearance of directed bonds also. This solution to the considered problems is still rough and incomplete, partly because of the low accuracy of the energy constants for the atoms and the insufficient allowance for their mutual arrangement. Further, the effect of the metallic nature of bonds has not yet been considered, and the study covers only the simplest binary compounds of elements. (Author)
