Abstract
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, The Periodic System of Chemical Elements. A History of the First Hundred Years, Elsevier, New York, 1969; Mazurs, Graphic Representations of the Periodic System during One Hundred Years, University Alabama Press, Alabama, 1974) or more recently on the Internet.
