Systematic Inorganic Chemistry OF THE FIFTH-AND-SIXTH-GROUP NONMETALLIC ELEMENTS by DON M. YOST frofessor of Inorganic Chemistry California Institute of Technology and HORACE RUSSELL, JR. Instructor in Chemistry California Institute of Technology New York PRENTICE-HALL, 1946 Preface Inorganic chemistry has undergone a marked transition in the last three decades as it has grown from an almost purely descriptive branch of science to a field in which all of the modern developments of physics and chemistry find application. In this field the quantum theory plays an important role in the establishment of energy states and molecular structures and in the explanation of the periodic law thermodynamics finds application in the prediction of the degree of completion of chemical reactions at equilibrium statistical mechanics makes possible the calcu lation of the thcrmodynamic properties of substances from atomic and molecular data and deepens our insight into the still unsolved problems of the rates of chemical reactions finally, the phenomena of natural and artificial radioactivity not only increase our knowledge of the funda mental structure of matter but also, through the use of radio-elements as tracers, greatly extend our understanding of the mechanisms of chemical reactions. From these considerations it is evident that any discussion of a chemical element or compound is complete only when the spectroscopic, structural, thcrmodynamic, chemical kinetic, and nuclear properties have been considered. In addition to these more modern aspects of the subject, due consideration must be given to the older, humbler, but nevertheless important, chemical facts that one finds in simple experiments with test tubes, beakers, and flasks. Since the field of inorganic chemistry embraces all of the chemical elements, a complete discussion of the whole subject would require volumes to record. Therefore, the authors have chosen to cover a selected list of chemical topics and to include in t
