Metals And Non Metals

This title introduces the reader to the properties of different materials. Find out how metals are extracted, learn about different refining techniques and discover how metals might be used in the future.

Presents the structure, uses, and origins of some of the most common nonmetallic elements.

The current textbook is an excellent inroduction to the chemistry of the non-metallic elements. The book begins by reviewing the key theoretical concepts of chemical bonding and the properties of different bonding types. Subsequent chapters are focused on reactions, structures and applications of the non-metallic compounds. Combining careful pedagogy and clear writing style, the textbook is a must-have for students studying inorganic chemistry.

This book is a new attempt to interrelate the chemistry of the non-metals. In the early chapters, simple compounds of the non-metals with the halogens, hydrogen, and oxygen are surveyed, permitting a large area of chemistry to be discussed without the burden of too many facts. The structural relationships in the elemental forms of the non-metals are then used as an introduction to the catenated compounds, including the boron hydrides. In the concluding chapter, selected heteronuclear chain, ring, and cage compounds are con sidered. In some chapters, we have thought it useful to outline important features of a topic in relation to chemical theory, before giving a more detailed ac count of the chemistry of individual elements. The book is certainly not comprehensive and the bias in the material selected probably reflects our interest in volatile, covalent non-metal compounds. Suggestions for furt her reading are presented in two ways. A selected bibliography lists general textbooks which relate to much of our subject matter. References in the text point to review articles and to a few original papers which we consider to be of special interest. Although there are few difficult concepts in the text, the treatment may be appreciated most by students with some previous exposure to a Group by Group approach to non-metal chemistry. We have assumed an elementary knowledge of chemical periodicity, bonding theory, thermodynamics, and spectroscopic methods of structure determination.

„Das Buch von Steudel bietet eine sehr lesenswerte und gut verständliche Darstellung wesentlicher Inhalte der Anorganischen Molekülchemie. Nach einer Einführung in die Chemische Bindung widmet sich das Werk der Stoffchemie der Hauptgruppenelemente.“ Prof. Dr. Michael Ruck, TU Dresden

Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities—chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a ‘foundational pillar’ of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.

Material undergoes the transformation from metal to non-metal or from non-metal to metal when environmental conditions, such as temperature and pressure, or the percentages of constituent components are changed. Such a transition is known as the metal-nonmetal (M-NM) transition. This book, 'The Physics of Metal – Nonmetal Transitions', explores the mechanisms so far discovered which cause the M-NM transition and presents a systematic discussion of them. All the mechanisms are discussed in terms of energy bands, and the band theory is introduced and explained in chapter 2. Once chapters 1 and 2 have been assimilated, the remaining chapters can be read independently of each other if required. The mechanisms discussed therein include the Peierls transition, the Bloch-Wilson transitions – types I and II respectively – the second of which was discovered by the author and her students. Subsequent chapters cover the Anderson transition and the Mott transition, and each chapter includes not only traditional theories, but also updated information about more recent research. The book can be used either as a textbook for undergraduate and postgraduate students of science and technology or as an introductory treatise for researchers in a wide variety of fields.
