What does matter look like at the molecular and atomic level? Why are leaves green? Why do colored fabrics fade upon repeated exposure to sunlight? Why does a pencil leave a mark when dragged across a sheet of paper? All of these basic questions have molecular answers that teach and illustrate chemical principles. Nivaldo Tro introduces each concept with a thought experiment, then develops the chemical principles and concepts involved in a molecular understanding of the experiment. Once students have grasped the basic concepts, they are introduced to consumer applications and environmental problems related to the concepts. Mathematical aspects of chemistry are optional.

Metal clusters are on the brink between molecules and nanoparticles in size. With molecular, nano-scale, metallic as well as non-metallic aspects, metal clusters are a growing, interdisciplinary field with numerous potential applications in chemistry, catalysis, materials and nanotechnology. This third volume in the series of hot topics from inorganic chemistry covers all recent developments in the field of metal clusters, with some 20 contributions providing an in-depth view. The result is a unique perspective, illustrating all facets of this interdisciplinary area: * Inter-electron Repulsion and Irregularities in the Chemistry of Transition Series * Stereochemical Activity of Lone Pairs in Heavier Main Group Element Compounds * How Close to Close Packing? * Forty-Five Years of Praseodymium Diiodide * Centered Zirconium Clusters * Titanium Niobium Oxychlorides * Trinuclear Molybdenum and Tungsten Cluster Chalcogenides * Current State of (B,C,N)-Compounds of Calcium and Lanthanum * Ternary Phases of Lithium with Main-Group and Late-Transition Metals * Polar Intermetallics and Zintl Phases along the Zintl Border * Rare Earth Zintl Phases * Structure-Property Relationships in Intermetallics * Ternary and Quaternary Niobium Arsenide Zintl Phases * The Building Block Approach to Understanding Main-Group-Metal Complex Structures * Cation-Deficient Quaternary Thiospinels * A New Class of Hybrid Materials via Salt Inclusion Synthesis * Layered Perrhenate and Vanadate Hybrid Solids * Hydrogen Bonding in Metal Halides * Syntheses and Catalytic Properties of Titanium Nitride Nanoparticles * Solventless Thermolysis * New Potential Scintillation Materials in Borophosphate Systems. With its didactical emphasis, this volume addresses a wide readership, such that both students and specialists will profit from the expert contributions.

The main goals of this text are to develop students' appreciation for the molecular world and stress the fundamental role it plays in our daily lives. It also strives to help students understand the major scientific, technological, and environmental issues affecting our society. To accomplish these goals, the author has made extensive efforts to clearly identify and explain connections between the molecular world and macroscopic world as well as between principles and applications. The Third Edition of CHEMISTRY IN FOCUS adds new pedagogy and technological resources, such as OWL for Liberal Arts, that further enhance learning and appreciation of the molecular world. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.

This second edition has been rewritten to provide a core textbook for all A Level Chemistry syllabuses. The topics are presented in manageable units, and there are practice and examination questions to help students check their progress. There is an introductory chapter to bridge the gap between GCSE and A Level, as well as summaries throughout the text. Activities are designed to assist learning, focusing on industrial development, social and economic contexts of chemistry.
