The Chemical Element: A Historical Perspective
37
 
 
The Chemical Element: A Historical PerspectiveOne 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.

The Periodic Table: Its Story and Its Significance
The Periodic Table: Its Story and Its Significance
The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the
periodic table by van Spronsen (1969), has been out of print for a onsiderable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and
interested lay-persons alike. The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been
interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to the classification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like Dobereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail. Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his
accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successive theories of the electron including Bohr's
quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early
electronic configurations published by Bohr and others. Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closes with an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain
such trends.
