Interviews conducted with Eric Scerri at the Chemical Heritage Foundation on the Periodic Table Part 1 Interviews conducted with Eric Scerri at the Chemical Heritage Foundation on the Periodic Table ...Part 2
This book contains key articles by Eric Scerri, the leading authority on the history and philosophy of the periodic table of the elements and the author of a best-selling book on the subject. The articles explore a range of topics such as the historical evolution of the periodic system as well as its philosophical status and its relationship to modern quantum physics. This volume contains some in-depth research papers from journals in history and philosophy of science, as well as quantum chemistry. Other articles are from more accessible magazines like American Scientist. The author has also provided an extensive new introduction in order to integrate this work covering a period of two decades. This must-have publication is completely unique as there is nothing of this form currently available on the market.
The periodic table provides a concise way of understanding how all known chemical elements react with one another and enter into chemical bonding, and it helps to explain the properties of each ...element that make it react in such a fashion. At the start of the 20th century, it was found that atomic number, rather than atomic weight, serves as the more correct criterion for ordering the elements in a linear sequence.\n At least three distinct threedimensional periodic systems have been developed and successfully marketed as educational tools.

Recent reports claiming to have observed textbook d orbitals are analyzed and it is argued that what was observed indirectly, and not for the first time, was actually electron density. It is also ...suggested that the tendency to use the terms electron density and orbital to mean the same thing will give rise to confusion in chemical education.
The relative virtues of 8- and 18-column periodic tables are discussed, followed by a brief mention of a 32-column table. Next, the left-step periodic table, as first introduced by Janet, is ...presented, as are the various attractive features of this representation. The advantages include what is termed here as the regularization of atomic number triads and a better rationalization of first-member anomalies. The distinction between simple substance and element is also explained as is the significance of this issue to the left-step table. Finally, I respond to some recent criticisms of previous work that I have published on atomic number triads of elements. It is becoming increasingly acknowledged that the discovery of the periodic table took place at the hands of at least six individuals working independently in different parts of the world (Scerri,
A Tale of Seven Scientists
, Oxford University Press, New York, 2016). In the intervening 150 or so years since the most well known of these tables were published, by Dmitri Mendeleev, at least 1000 periodic systems have appeared either in print form (Van Spronsen,

).
Since the periodic table has reached the ripe old age of 150 years it may be an appropriate time to look back at the development of this unique scientific icon. It is also an opportunity to look ...forwards to any changes that the periodic table may undergo in view of the ever-growing list of new elements that continue to be synthesized. The way that the past and future will be examined in this article will be to follow a main thread that focuses on the number of columns in the periodic table at various stages in its development.
