  • The Periodic Table: A Very Short Introduction - 2. A quick overview of the modern Periodic Table
    The Periodic Table: A Very Short Introduction, 2019
    Co-Authors: Eric R. Scerri
    Abstract:

    ‘A quick overview of the modern Periodic Table’ explains the arrangement of elements in the Periodic Table, and introduces the concept of Periodic law. Elements were originally ordered by their equivalent weight, but this was superseded by atomic weight, and then atomic number. There are many versions of the Periodic Table, but all obey Periodic law, which states that after certain regular, but varying intervals, the chemical elements show an approximate repetition in their properties. Developments in physics, especially quantum mechanics and relativity, have changed the way we think about elements and Periodicity. The number of known elements has increased to 118 as the result of the synthesis of artificial elements.

  • 6. Physics invades the Periodic Table
    The Periodic Table: A Very Short Introduction, 2019
    Co-Authors: Eric R. Scerri
    Abstract:

    ‘Physics invades the Periodic Table’ assesses the impact of key discoveries in physics on the understanding of the Periodic Table. Ernest Rutherford provided evidence for the nuclear structure of atoms, and also determined that the charge of an atom is equal to half its atomic weight. Anton van den Broek linked this principle to the number of protons in a nucleus, thus devising the notion of atomic number. Henry Moseley quantified this principle, and used it to show exactly how many elements would fill the gaps in the Periodic Table. Radioactive experiments created new forms of elements with different weights but the same charge, which Frederick Soddy identified as isotopes.

  • 10. Forms of the Periodic Table
    The Periodic Table: A Very Short Introduction, 2019
    Co-Authors: Eric R. Scerri
    Abstract:

    ‘Forms of the Periodic Table’ discusses some of the different Periodic Tables that have been published and asks whether there is an ‘optimal’ Periodic Table. Meaningful differences only occur when one changes the order of the elements. Examples include moving the positions of hydrogen and helium to better reflect their chemical properties, or the shifting of elements to form triads of similar behaviour. Whether an optimal Periodic Table exists depends ultimately on one’s philosophy. Realists believe that the repetition of chemical properties is an objective fact, and so strive for the most accurate depiction of it. Instrumentalists believe that such depictions are simply a human construct and not ultimately important.

  • The Periodic Table: A Very Short Introduction - 4. Steps towards the Periodic Table
    The Periodic Table: A Very Short Introduction, 2019
    Co-Authors: Eric R. Scerri
    Abstract:

    ‘Steps towards the Periodic Table’ outlines the different versions of the Periodic Table that were devised in the 1860s following the Karlsruhe conference in Germany, which introduced standardized atomic weights. De Chancourtois actually discovered Periodicity, but his ideas did not gain traction for many years. Newlands devised the law of octaves, but the musical analogy garnered ridicule from academics. Odling made important discoveries in Periodicity, but lacked enthusiasm for the idea. Hinrichs used his wide range of interests to postulate that the ratios of atomic size could explain each element’s unique spectral fingerprint. Meyer made huge strides in discovering Periodicity, but, due to a misplaced Table, did not get the recognition he deserved.

  • The Earth Scientist’s Periodic Table of the Elements and Their Ions: A New Periodic Table Founded on Non-Traditional Concepts
    Mendeleev to Oganesson, 2018
    Co-Authors: L. Bruce Railsback
    Abstract:

    The Earth Scientist’s Periodic Table of the Elements and Their Ions is a fundamentally new Table that was first published in 2003 in the Geological Society of America’s (GSA) prominent journal Geology (Railsback 2003). The new Table was reported in Nature, it was featured in a cover article by Science News, it was included among Discover magazine’s 100 Top Science Stories of 2003, and its publication was noted in many other magazines and online outlets. GSA sold a large number of reprints of the 2003 paper and then, in 2004, published a revised version of the Table in GSA’s Map and Chart Series (Railsback 2004). When GSA’s printed stock ran low, the Society published a further revised version of the Table in its Map and Chart Series in 2011 (Railsback 2011). The Table has been translated into Chinese (Jin 2006), Spanish (Bernal and Railsback 2008), Portuguese (Franco de Souza Lima and Railsback 2012), and German. The original 2003 paper has been cited in journals ranging from Journal of Mathematical Chemistry to Carbohydrate Research to Geomicrobiology Journal to Journal of Arid Environments to Resource Geology to Reviews in Geophysics, and it has proven useful in understanding the topology of the Periodic Table (Restrepo et al. 2006). The success of the new Earth Scientist’s Periodic Table of the Elements and Their Ions across the past decade suggests that the Periodic Table, as a general concept, is not a static document but instead is still subject to evolution, especially as scientific fields beyond traditional chemistry increasingly use chemical perspectives. It further suggests that volumes like this one are not simply retrospective ruminations on a nineteenth-century invention, but instead they can be part of an ongoing process to find new meaning in the Periodic concept and to make it more applicable in broader contexts in the twenty-first century. Despite the diversity of Periodic Tables produced over the last 140 years (e.g., Mazurs 1974), the Earth Scientist’s Periodic Table of the Elements and Their Ions differs both in conceptual origin and in form from almost all previous versions.

  • The Periodic Table, Zeolites and Single-Site Heterogeneous Catalysts
    2019
    Co-Authors: John Meurig Thomas
    Abstract:

    This brief account of the way in which the Periodic Table has guided the design of new and the improvement of existing heterogeneous catalysts should be regarded as a companion to that composed by Gómez-Hortigüela and Pérez-Pariente (Synthesis and properties of zeolitic materials guided by Periodic considerations, this volume). It has been structured in such a manner as to serve as an introduction to reference (Gómez-Hortigüela and Pérez-Pariente, Synthesis and properties of zeolitic materials guided by Periodic considerations, this volume). A recapitulation is given of the salient features of zeolites, and of the qualitative way, initially, the catalytic community set about exploiting trends in the Periodic Table to design new heterogeneous catalysts and to expand the performance of existing ones. Later sections deal with the unique opportunities presented by zeotypes, in conjunction with the Periodic Table, of fashioning new, high-performance and selective catalysts of a variety of kinds. Of those, single-site heterogeneous catalysts (SSHCs) exhibit a number of important advantages, which are illustrated by specific examples.

  • Glass: Home of the Periodic Table.
    Frontiers in chemistry, 2020
    Co-Authors: Georgiy Yu. Shakhgildyan, A. S. Lipatiev, Sergey V. Lotarev, S. S. Fedotov, Vladimir N. Sigaev
    Abstract:

    Glass is the most common material around us, and humankind uses it every day for more than 5000 years. However, from the chemical point of view, glass is the only material that could represent almost all elements of the Periodic Table inside itself, showing the effect of the Periodic Law on properties of the final material. In this paper, we show the most remarkable examples demonstrating that glass can rightfully be called "home" for all chemical elements providing different properties depending on its composition. We gave a new look at the Periodic Table and described how a small number of glass-forming components creates unique glass structure which could enclose almost all remaining elements including transition and noble metals, lanthanides and actinides as modifying components providing an inconceivable number of discoveries in material science. Moreover, we reviewed a series of studies on the direct femtosecond laser writing in glasses which paves the way for a redistribution of chemical elements in the spatially confined nanosized zone in glass volume providing unique properties of laser-induced structures. Finally, for the first time, we reproduce the Periodic Table in birefringence colors in the bulk of silica glass using a direct laser writing technique. This image of 3.6 × 2.4 mm size can withstand temperature up to 900°C, humidity, electromagnetic fields, powerful cosmic and reactor radiation and other environmental factors and demonstrates both the art of direct laser writing and symbolic role of glass as the safest and eternal home for the Periodic Table.
