MOLECULES AND THE CHEMICAL BOND & Other Leading Chemical Concepts Simplified This highly original book by a noted chemist and chemical educator may change the way newcomers to chemical thought learn and the way its connoisseurs think about - * Atomic Theory * The Mole Concept and Avogadro's Constant * The Gas Laws * Solving Problems in Chemical Stoichiometry * The Saturation and Directional Character of Chemical Affinity * The Pauli Exclusion Principle * Linnett's Double Spin Set Theory * Pauling's Rules of Crystal Chemistry * The Octet Rule * Lewis Structures for O2, NO, CO, SO2 and SO3 * Construction of Bond Diagrams * VSEPR Theory * Dative Bonding * Multicenter Bonding * Bonding in Metals * pH Calculations * The Periodic Table * The Energy Function and the First Law of Thermodynamics * The Entropy Function and the Second Law of Thermodynamics * How an Inductive Science Advances Dedicated to students, teachers, and professionals in the pure and applied sciences who might welcome an account of molecular structure that, in Einstein's words is as simple as possible but [it's believed] no simpler and that provides, thereby, in Gibbs' words, a point of view from which the subject appears in its greatest simplicity, MCB is several books interlaced. It is a novel account of evidence for atoms; an historical account of the development classical structural theory of molecules; a simple, step-by-step guide on how to draw scientifically sound bond diagrams; an exclusive orbital model of bonding that embraces from one point of view covalent, ionic, and metallic bonding; philosophical justifications for uses of molecular models; explanations for a number of previously unexplained molecular features; domestication for easy use in valence theory of fundamental principles of quantum physics; and, withal, a short textbook of general chemistry in a new key. Principally MCB is a highly visual account of a chemical mechanics of the Pauli Exclusion Principle, in the form of the story of a stroke, a stick, and a sphere and what happens if one takes chemists' seemingly unsophisticated cartoons of molecules and their corresponding tinker-toy-like ball-and-stick models seriously. One theme runs through the book: the nature of the inductive sciences, illustrated by the union of facts and ideas with creation of concepts and models, principles and rules that, jointly, comprise what is called in MCB "Conceptual Valence Bond Theory". The book has been described "as a pedagogical hierarchy of progressively more sophisticated treatments of an easily visualizable model of the chemical bond." In the words of the author's daughter (a chemist) - "This book is the culmination of my Father's insights into the molecules he has literally breathed, consumed, and digested, for the past 84 years. It is his intimate knowledge about the elements, learned from a lifetime of reading, experimenting, and teaching that makes this book different. Dad truly loves (and believes in!) molecules, and that single tenet comes across on every page. Flat valence stroke diagrams are inflated to three dimensional valence sphere models whose geometries correlate with calculations and provide, with ease, explanations for reaction mechanisms, multicenter bonds, and molecular geometries considered exceptions or unexpected . Describing molecules as hypervalent or electron deficient suggests something abnormal or unnatural, and is misleading since nature is always natural . Concepts such as the gas laws and the energy function are presented from an historical perspective, and with algebraic rigor, eliminating inconsistencies that bug you as a chemistry student, but you can't really put your finger on why. From the correct placement of helium above beryllium in the periodic table, to pointing out the problems with omitting nucleus-electron attractions in the popular Valence Shell Electron Pair Repulsion theory (where correct conclusions regarding molecular shapes support an incorrect conce

This book addresses the problem of teaching the Electronic Structure and Chemical Bonding of atoms and molecules to high school and university students. It presents the outcomes of thorough investigations of some teaching methods as well as an unconventional didactical approach which were developed during a seminar for further training organized by the University of Bordeaux I for teachers of the physical sciences.The text is the result of a collective effort by eleven scientists and teachers: physicists and chemists doing research at the university or at the CRNS, university professors, and science teachers at high-school or university level.While remaining wide open to the latest discoveries of science, the text also offers a large number of problems along with their solutions and is illustrated by several pedagogic suggestions. It is intended for the use of teachers and students of physics, chemistry, and of the physical sciences in general.

This book deals with the electron density distribution in molecules and solids as obtained experimentally by X-ray diffraction. It is a comprehensive treatment of the methods involved, and the interpretation of the experimental results in terms of chemical bonding and intermolecular interactions. Inorganic and organic solids, as well as metals, are covered in the chapters dealing with specific systems. As a whole, this monograph is especially appealing because of its broad interface with numerous disciplines. Accurate X-ray diffraction intensities contain fundamental information on the charge distribution in crystals, which can be compared directly with theoretical results, and used to derive other physical properties, such as electrostatic moments, the electrostatic potential and lattice energies, which are accessible by spectroscopic and thermodynamic measurements. Consequently, the work will be of great interest to a broad range of crystallographers and physical scientists.

Molecular surface science has made enormous progress in the past 30 years. The development can be characterized by a revolution in fundamental knowledge obtained from simple model systems and by an explosion in the number of experimental techniques. The last 10 years has seen an equally rapid development of quantum mechanical modeling of surface processes using Density Functional Theory (DFT). Chemical Bonding at Surfaces and Interfaces focuses on phenomena and concepts rather than on experimental or theoretical techniques. The aim is to provide the common basis for describing the interaction of atoms and molecules with surfaces and this to be used very broadly in science and technology. The book begins with an overview of structural information on surface adsorbates and discusses the structure of a number of important chemisorption systems. Chapter 2 describes in detail the chemical bond between atoms or molecules and a metal surface in the observed surface structures. A detailed description of experimental information on the dynamics of bond-formation and bond-breaking at surfaces make up Chapter 3. Followed by an in-depth analysis of aspects of heterogeneous catalysis based on the d-band model. In Chapter 5 adsorption and chemistry on the enormously important Si and Ge semiconductor surfaces are covered. In the remaining two Chapters the book moves on from solid-gas interfaces and looks at solid-liquid interface processes. In the final chapter an overview is given of the environmentally important chemical processes occurring on mineral and oxide surfaces in contact with water and electrolytes. Gives examples of how modern theoretical DFT techniques can be used to design heterogeneous catalysts This book suits the rapid introduction of methods and concepts from surface science into a broad range of scientific disciplines where the interaction between a solid and the surrounding gas or liquid phase is an essential component Shows how insight into chemical bonding at surfaces can be applied to a range of scientific problems in heterogeneous catalysis, electrochemistry, environmental science and semiconductor processing Provides both the fundamental perspective and an overview of chemical bonding in terms of structure, electronic structure and dynamics of bond rearrangements at surfaces

In recent years mineralogy has developed even stronger links with solid-state chemistry and physics and these developments have been accompanied by a trend towards further quantification in the theoretical as well as the experimental aspects of the subject. The importance of solid-state chemistry to mineralogy was reflected in a symposium held at the 1982 Annual Congress of The Royal Society of Chemistry at which the original versions of most of the contributions to this book were presented. The meeting brought together chemists, geologists and mineralogists all of whom were interested in the application of modern spectroscopic techniques to the study of bonding in minerals. The interdisci plinary nature of the symposium enabled a beneficial exchange of information from the various fields and it was felt that a book presenting reviews of the key areas of the subject would be a useful addition to both the chemical and mineralogical literature. The field of study which is commonly termed the 'physics and chemistry of minerals' has itself developed very rapidly over recent years. Such rapid development has resulted in many chemists, geologists, geochemists and mineralogists being less familiar than they might wish with the techniques currently available. Central to this field is an understanding of chemical bonding or 'electronic structure' in minerals which has been developed both theoretically and by the use of spectroscopic techniques.
