"This resource book by Krebs is a very informative, well-written review of the chemical elements that make up Earth. This new edition (1st ed., CH, Jul'98, 35-6235), expanding the previous version, is written in a style that is understandable to laypersons and those interested in basic chemistry. The initial sections provide a brief but comprehensive history of chemistry, the history of atomic structure and its theoretical models, and a history and organization of the periodic table of the elements, followed by the comprehensive discussion of each of the chemical elements. The history of each element, arranged according to its appearance in the periodic table, is provided along with its physical and chemical characteristics, source and abundance, usefulness, and hazards. This book should be in every undergraduate library and even in public libraries. Highly recommended. General readers; lower- and upper-division undergraduates; professionals; two-year technical program students." - Choice
