Book excerpt: "Imagination and shrewd guesswork are powerful instruments for acquiring scientific knowledge . . . " 1. H. van't Hoff The last decades have witnessed a rapid growth of quantum chemistry and a tremendous increase in the number of very accurate ab initio calculations of the electronic structure of molecules yielding results of admirable accuracy. This dramatic progress has opened a new stage in the quantum mechanical description of matter at the molecular level. In the first place, highly accurate results provide severe tests of the quantum mecha nics. Secondly, modern quantitative computational ab initio methods can be synergetically combined with various experimen tal techniques thus enabling precise numerical characterization of molecular properties better than ever anticipated earlier. However, the role of theory is not exhausted in disclosing the fundamental laws of Nature and production of ever increasing sets of data of high accuracy. It has to provide additionally a means of systematization, recognition of regularities, and ratio nalization of the myriads of established facts avoiding in this way complete chaos. Additional problems are represented by molecular wavefunctions provided by the modern high-level computational quantum chemistry methods. They involve, in principle, all the information on molecular system, but they are so immensely complex that can not be immediately understood in simple and physically meaningful terms. Both of these aspects, categorization and interpretation, call for conceptual models which should be preferably pictorial, transparent, intuitively appealing and well-founded, being sometimes useful for semi quantitative purposes.

Available in PDF, EPUB and Kindle. Book excerpt: The molecular structure hypothesis - that a molecule is a collection of atoms linked by a network of bonds - was forged in the crucible of nineteenth century experimental chemistry and has continued to serve as the principal means of ordering and classifying the observations of chemistry. There is a difficulty with the hypothesis, however, in that it is not related directly to the physics which governs the motions of the nuclei and electrons that make up the atoms and the bonds. It isthe purpose of this important book - now available in paperback for the first time - to show that a theory can be developed to underpin the molecular structure hypothesis - that the atoms in a molecule are real, with properties predicted and defined by the laws of quantum mechanics can be incorporated into the resulting theory - a theory of atoms in molecules. The book is aimed at those scientists responsible for performing the experiments and collecting the observations on the properties ofmatter at the atomic level, in the belief that the transformation of qualitative concepts into a qualitative theory will serve to deepen our understanding of chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Atomic and Nuclear Chemistry, Volume 1: Atomic Theory and Structure of the Atom presents the developments in classical atomic chemistry in the 19th century. This book discusses the atomic theory in terms of existing ideas on nuclear structure and the wave mechanics of electrons in atoms. Organized into six chapters, this volume begins with an overview of the origin of the atomic theory. This text then explores Berzelius's atomic weight tables. Other chapters consider Dalton's conception of an atom as a hard dense sphere. This book discusses as well the significant results of the simple wave mechanical treatment. The final chapter deals with the determination of the Avogadro's number, which enabled the actual masses of atoms and molecules to be determined. This book is a valuable resource for atomic physicists, chemists, and research workers. First-year university students who are taking chemistry as a subsidiary subject will also find this book useful.
Download or read book Atoms and Molecules written by Chris Woodford and published by The Rosen Publishing Group, Inc. This book was released on 2012-07-15 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greek philosophers first hypothesized that matter was composed of atoms, but the theory would not resurface again until the late 17th century. The idea that that atoms joined to form structures called molecules first appeared in the 19th century and helped explain why gases, liquids, and solids behave differently from one another. In the 20th century subatomic particles were discoveredelectrons, protons, and neutronsand atomic structure was finally understood. These breakthroughs led to the development of quantum theory and quantum mechanics. This book details the inspiring and heroic discovery, delving deeply into intriguing stories, reviewing major scientific landmarks, and introducing readers to the vivid men and women who helped discover and map the microscopic universe that is the atom. Supplemental content includes an activity spread, a substantial and highly detailed timeline, and a list of key people with mini-biographies.
