This manuscript, originally intended as a second edition of "Chemical Periodicity" (1960), has been so extensively revised and contains 'so many important additions, that the hook has been published under a new title. This version has been expanded by 100 pages. As before, many of the properties of binary compounds are displayed in periodic table farm. These include, melting and boiling points, heats of formation, partial charges on the atoms, hond lengths, and atomiaation energies. The ohvsical orooerties of the elements
n full page in most instznces. The first two chapters, Atomic Strnct,nre and the Periodic Law, and Nonpolar Covalence, contain a rather condensed version of what has become a conventional approach to the wave mechanical atom and chemical bondingin inorganic texthooks. They bake t,he reader up to a. moleadar orbit,al description of the honding in simple diatomic molecules. The occurrence, structure, and physical properties of the "on-metala and metala are described in t,he next two chapters, followed by a chapter on the Periodicity of Physical Properties of the Elements. Chapter 6 is devoted t,o topics which are of prime importance to the rest of the text, namely, elect,ronegrttivit,y, hond polarity, and partial charge. The usefulness of the text depends in large part on the readers acceptance of the author's approach to these subjects. The author ha4 refined his calculations of electronegativity values and extended them to include the transition elements. The partial charge data are used to rationalize the physical and chemical ~praperties of the binary compounds. The data also have been nsed to calculate the total bond energies of more than 250 gaseous and solid cnmpo~mds. I n Chapter 7 the author turns to Principles of Coordination Chemistry, which includes a brief review of ligand field theory and a molecular orbital description of the bonding involved in complex compoonds. Mol&ular and crystal structure are cow sidered next in t,erms of the general geometries expected for molecular species, and t,ypical structures of ionic 8olids. I n the next chapter (9) hond energy and "ionic" bonding are considered. The Born-Haber approach to ionic solids is modified to accommodate a covalent can-
very goad agreement with experimental data. In Chapter 10 on Principles of Chemical React,ians, the role of entropy and enthalpy changes are assessed in terms of hond strength, lengths, polarity, and multiplicity. Solution Chemistry (Cbntinued on page A898) Volume 45, Number 9, September 1968
