In inorganic chemistry, emphasis should be placed on the connections between valence shell electron configuration and the physical and chemical properties of the element. This book is a short, concise work which emphasizes these connections, in particular the chemistry of the Main Group compounds. With reference to chemical properties, Lewis Structures, stoichometry and spider diagrams, students should be able to predict or calculate the chemistry of simple polyatomic compounds from the valence shell configuration and will no longer be required to memorize vast amounts of factual chemistry. Aimed at students taking chemistry as a subsidiary subject as well as honours degree students, this text is accompanied by CAL tutorials which can be downloaded free.
