Paper eight first appeared in the Journal of Chemical Education in 2008. Whereas in my book on the periodic table, I recommended the left-step table as the best possible representation, I subsequently changed my mind and proposed a new table. First of all let me say why I initially supported the left-step table. My attention was first drawn to the left-step table by Henry Bent s unpublished booklets on the subject, although I felt that his...

ABSTRACT This article concerns various foundational aspects of the periodic system of the elements. These issues include the dual nature of the concept of an "element" to include element as a "basic substance" and as a "simple substance." We will discuss the question of whether there is an optimal form of the periodic table, including whether the left-step table fulfils this role. We will also discuss the derivation or explanation of the [n + , n] or Madelung rule for electron-shell filling and whether indeed it is important to attempt to derive this rule from first principles. In particular, we examine the views of two chemists, Henry Bent and Eugen Schwarz, who have independently addressed many of these issues. 2008 Wiley Periodicals, Inc.

I would like to thank Eugen Schwarz and Henry Bent for discussion over several years. 

I acknowledge many scholars of the periodic table from diverse fields, including Peter Atkins, Henry Bent, Bernadette Bensaude, Nathan Brooks, Edwin Constable, John Emsley, Michael Gordin, Ray Hefferlin, William Jensen, Herbert Kaesz, Masanori Kaji, Maurice Kibler, Bruce King, Mike Laing, Laurence Lavelle, Guillermo Restrepo, Dennis Rouvray, Oliver Sacks, Eugen Schwarz, Philip Stewart, Mark Winters and many others. 

Nearly four decades ago, American chemist Henry Bent40 formulated a remarkable principle that relates atomic hybridization to substituent electronegativity. This principle, now called Bent s rule, was originally expressed in the following words ... 

Linear triatomic anions The pioneering crystallographic studies of Odd Hassel140 on trihalides and related donor-acceptor species led to a far-reaching analysis of such Hassel compounds by Henry Bent.141 The triiodide ion (I3-, stable in aqueous solution) and other known linear trihalide XYZ- species also served as the prototype for Pimentel s incisive three-center MO analysis of hypervalency. We shall therefore begin with NBO/NRT investigation of a series of hypervalent and non-hypervalent triatomic anions in order to make contact with these classic studies. While ab initio studies add many quantitative details to the understanding of these species, the basic picture sketched by Bent and Pimentel is found to be essentially preserved. 

Thus thermodynamics tells us the work potential of a process and then tells us that we can never achieve this potential. In this spirit, thermodynamicist Henry Bent has paraphrased the first two laws of thermodynamics as follows ...
