Presented is a modern view of chemistry suitable for pupils with a wide range of skills and abilities. The outline of topics provides the unifying principles of chemistry together with related facts. The principles included in the outline are basic to man's understanding of his environment. The topical outline is divided into nine major units: Matter and Energy, Atomic Structure, Bonding, Periodic Table, Mathematics of Chemistry, Kinetics and Equilibrium, Acid-Base Theories, Redox and Electrochemistry, and Organic Chemistry. A tenth unit, Application of Principles of Reaction, is to be related to, and integrated into, other units as it applies. Each unit is subdivided into specific topics, each of which has additional material associated with it. Understandings and Fundamental Concepts outline the basic concepts, while Supplementary Information provides amplification and explanation of the basic concepts. (Author/HM)
