Samenvatting:

All aspects of the chemical elements are presented in this easy-to-use reference for high school and college students. This one-volume work covers the development of chemistry as a science and the growth of the Periodic Table from pre-history to present day. Included are descriptions of the most recently discovered elements, which provide information on each element usually found only by consulting different sources. This information includes symbol, atomic number, common valence, atomic weight, natural state, common isotopes, characteristics, abundance, history, common uses, examples of common compounds, and hazards. Schematic diagrams of each of the elements through number 103 accompany their descriptions. Krebs introduces the user to the background of how we came to know and understand the chemical nature of Earth and everything in the universe. He also examines the present concerns about the effects of chemicals on the Earth's environment. The elements are arranged according to their placement on the Periodic Table, which enables the user to examine the similarities and differences of elements found in different groups, periods, and series of the Periodic Table. A comprehensive glossary as well as appendixes and an index provide easy access for student users.
