The Chemical Element: A Historical Perspective
Andrew Ede, "The Chemical Element: A Historical Perspective (Greenwood Guides to Great Ideas in Science)"
Greenwood Press | 2006 | ISBN: 0313333041 | 200 pages | PDF | 2,1 MB
One of the most familiar features of any high-school chemistry lab is the Periodic Table of Elements. Elegant, informative, useful to any student in the lab - the Periodic Table neatly summarizes our scientific knowledge of the chemical elements from hydrogen to uranium and beyond - atomic number, atomic weight, isotopes, and more. But how did scientists discover all of these features of the elements? How did the Periodic Table come to be? And, even more basically, how did the concept of the chemical element come to dominate how scientists understand chemistry? This book shows readers the answers to these and other questions regarding the scientific understanding of matter. The Chemical Element, a volume in the Greenwood Guides to Great Ideas in Science, traces the history of this tremendously powerful concept from the ancient philosophers to the present day.
