"The third edition of this widely acclaimed reference book collects together the most important facts about all the chemical elements in a single volume. In addition to chemical, physical, nuclear, and electron data, this edition includes new sections on crystal, biological, and geological data. The alphabetical format of the earlier versions has been retained. Also included are the six newly approved IUPAC names of the elements 104-109; rutherfordium, dubnium, seaborgium, bohrium, hassium, and meitnerium." "This handy reference guide is for chemists, physicists, spectroscopists, geologists, life scientists, and environmentalists."--Jacket.
