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 considerable 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 Döbereiner 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.

In 1913, English physicist Henry Moseley transformed our understanding of the elements by organizing them by atomic number, from hydrogen to uranium. However, it soon became obvious that researchers had yet to discover seven completely unknown elements. In this updated and expanded edition of his acclaimed book, Eric Scerri presents the intriguing stories of these elements--protactinium, hafnium, rhenium, technetium, francium, astatine, and promethium. It follows their discoveries through the two world wars, starting with protactinium in 1917 and ending with promethium in 1945. Scerri details the research leading to each discovery, the pivotal experiments, the chemists involved, the properties of each element, and their applications. For example, hafnium alloys, named after Copenhagen (hafnia), have some of the highest boiling points and are used in rocket thrusters like those on the Apollo Lunar Modules. Scerri then examines the integration of twenty-five new elements into the periodic table over the past fifty years and concludes with a new chapter on rare earth elements and the histories of their discoveries. The Second Edition of A Tale of Seven Elements vividly portrays the journey of chemical research, from missteps and disputes to the thrill of discovery, illuminating the researchers behind the elements, as much as their breakthroughs.

The periodic table of elements, first encountered by many of us at school, provides an arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, and divided into periodic trends. In this Very Short Introduction Eric R. Scerri looks at the trends in properties of elements that led to the construction of the table, and shows how the deeper meaning of the table's structure gradually became apparent with the development of atomic theory and, in particular, quantum mechanics, which underlies the behaviour of all of the elements and their compounds. This new edition, publishing in the International Year of the Periodic Table, celebrates the completion of the seventh period of the table, with the ratification and naming of elements 113, 115, 117, and 118 as nihonium, moscovium, tennessine, and oganesson. Eric R. Scerri also incorporates new material on recent advances in our understanding of the origin of the elements, as well as developments concerning group three of the periodic table.
