Daubeny's Teaching Display Board & Wooden Cubes of Atomic Weights

The Museum of the History of Science, Oxford, has a display of Charles Daubeny's teaching materials, including a black painted wooden board with "SYMBOLS OF SIMPLE BODIES": showing symbols, atomic weights and names of elements in two columns, and a small pile of cubes with element symbols.

Charles Daubeny and Chemistry at the Old Ashmolean

Charles Daubeny (1795-1867) was appointed Aldrichian Professor of Chemistry at Oxford in 1822. In 1847 he moved from the original laboratory in this basement [in the museum] to a new one built at his own expense at the Botanic Garden. His apparatus went with him and was preserved there. Daubeny actively campaigned for the teaching of science in Oxford and held several professorships in addition to chemistry. He also conducted research on subjects such as photosynthesis.

From the HSM Database (Inventory no. 17504):

DAUBENY'S LIST OF ATOMIC WEIGHTS Wooden panel, black with white lettering, listing in two columns the symbols and names of twenty elements. This lecture board is identical to the table in the third edition (1831) of E. Turner, 'Elements of Chemistry', apart from the atomic weight for bromine. Daubeny wrote a useful 'Introduction to the Atomic Theory' (published in three versions: 1831, 1840, and 1850), the first edition of which also quotes Turner's table. Probably contemporary with this lecture board are the wooden cubes with the symbols for certain elements.

The period from 1810 to 1860 was crucial in the development of the periodic table. Most of the main group and transition elements had been discovered, but their atomic weights and stoichiometries (combining ratios) had not been fully deduced. Oxygen was assumed to have a weight of 6, and consequently carbon is assumed to have a mass of 6.

Daubeny's element symbols and weights – along with the modern mass data – are tabulated:

While quite a number of weights are close to the modern values, many are way out. However, the error is usually a stiotoimetric factor error.

From the HSM Database (Inventory no. 33732): SET OF WOODEN CUBES ILLUSTRATING ATOMIC WEIGHTS

Forty-two wooden cubes numbered 1-42, painted black with symbols for certain elements, compounds or radicals painted in white on the faces, together with the corresponding atomic, molecular or radical weights. The face markings appear in various combinations:

A typical cube (no. 3) may be represented by the following figure. They present something of an enigma as their faces do not form an obvious pattern. The numbers indicate that there were 42 cubes. In style they are similar to the figures on the panel of atomic weights.

The cubes are listed in Daubeny's 1861 catalogue, p. 11 as: "Wooden cubes for illustrating atomic weight". [See D. R. Oldroyd, The Chemical Lectures at Oxford (1822-1854) of Charles Daubeny, M.D., F.R.S. Notes and Records of the Royal Society, vol. 33 (1979), pp. 217-259.]

This display was spotted by Eric Scerri who was visiting the museum with Mark Leach in 2010.

There is a virtual tour on the museum, and the above display is in the basement.

Meyer's Periodic System

In his book, The Periodic Table: A Very Short Introduction, Eric Scerri writes how Lothar Meyer devised a partial periodic tables consisting of 28 elements arranged in order of increasing atomic weight in which the elements were grouped into vertical columns according to their chemical valences:

Naquet's Families of Elements

According to Naquet’s 1864 textbook, Principes de Chimie, F. Savy, Paris, (updated by Eric Scerri):

Spectroscope Revelations

From Scientific American in 1866, an article by Henry Draper concerning "The Spectroscope and Its Revelations".

At the time there was no understanding how the spectra were generated but it was recognised that every element produced a unique spectrum. Over 35,000 stars are catalogued/identified by their "HD" [Henry Draper] numbers:

Hinrichs' Programme of Atomechanics

Gustavus Detlef Hinrichs' spiral "Programme of Atomechanics". Programm der Atomechanik oder die Chemie eine Mechanik de Pantome, Augustus Hageboek, Iowa City, IA (1867).

Hinrichs' system is based on the relationship of what he called: "pantogens, with its atoms called panatoms, which explains the numerical relations of atomic weights and gives a simple classification of the elements."

This classification system culminated in 1867 in his spiral periodic table, which better clarified the groupings of elements. Hinrichs' classification, while distinctly different from the other periodic tables of this period, "seems to capture many of the primary periodicity relationships seen in the modern periodic table... it is not cluttered by attempts to show secondary kinship relationships." (Scerri)

Meyer's "Lost" Table of 1868

In his book, The Periodic Table: A Very Short Introduction, Eric Scerri writes how Lothar Meyer produced an expanded periodic system for his1868 textbook which contained 53 elements. Unfortunately, the table was misplaced by the publisher and was not appear until after his death in 1895:

Klieber's Cosmochemical Periodic Table

Klieber's qualitative synthesis of the general composition of celestial objects in the form of a plane periodic system following atomic numbers. His diagram is probably one of the earliest versions of a "cosmochemical periodic table". (The diagram below is clearly redrawn as it has a very modern style.)

Werner's Arrangement

Werner's Arrangement is the first modern looking PT formulation. It appeared before the structure of the atom was known, before the importance of atomic number was recognised and before quantum mechanics had been developed.

Berichte der Deutschen Chemischen Gesellschaft (1905), 38, 914-21 and J. Chem. Soc., Abstr. 88, II, 308-9 1905:

From Quam & Quam's 1934 review paper.pdf

Eric Scerri comments that the interesting features are:

• A remarkably modern looking formulation in that it separates not only the transition metals but also the rare earths into separate blocks to give what we would now call a "long-form 32 column table". Except Werner guessed wrong as to how many rare earths exist, with the result that he shows 33 groups.
• This formulation is also interesting for showing an element between H and He and two elements before H.
• Werner computed the average gaps between atomic weights for the second through the fifth periods as 1.85, 2.4, 2.47 and 2.5, respectively.
• From this he extrapolated the gap for the first period as 1.5, which coincidentally was also half the difference between the atomic weights of H and He. Werner thus predicted a new element with atomic weight 2.5.
• Moseley's work of 1913 showed there were no elements before H and none between H and He.

van den Broek Periodic Table 1

From Wikipedia: Antonius Johannes van den Broek (1870-1926) was a Dutch amateur physicist notable for being the first who realized that the number of an element in the periodic table (now called atomic number) corresponds to the charge of its atomic nucleus. The 1911 inspired the experimental work of Henry Moseley, who found good experimental evidence for it by 1913. van den Broek envisaged the basic building block to be the 'alphon', which weighed twice as much as a hydrogen atom.

Cherkesov: Two Periodic Tables

von Bichowsky FR, The place of manganese in the periodic system, J. Am. Chem. Soc. 1918, 40, 7, 1040–1046 Publication Date: July 1, 1918 https://doi.org/10.1021/ja02240a008 

René Vernon writes:

"In this curious article, von Bichowsky, a physical chemist (1889-1951), mounted an argument for regarding Mn as belonging to group 8 (see table 1 below) rather than group 7 (table 2). His article has effectively been assigned to the dustbin of history, having apparently gathered zero citations over the past 103 years.

"Items of note in his 24-column table:

• While Mn, 43 and 75 are assigned to group 8 they remain in alignment with group 7. Se is shown as Sc
• 14 lanthanides, from Ce to Yb, make up group 3a; If La and Lu are included, there are 16 Ln
• Gd is shown as Cd
• Positions of Dy and Ho have been reversed
• Tm and Tm2
• Po shown as "RaF"
• Ra shown as "RaEm"
• Pa shown as Ux2

von Bichowsky made his argument for Mn in group 8, on the following grounds:

• by removing the Ln from the main body of the table all of the gaps denoted by the dashes (in table 2) were removed
• the eighth group links Cr with Cu; Mo with Ag; and W with Au
• the symmetry of the table is greatly increased
• the triads are replaced by tetrads and a group of 16 Ln which accords better with "the preference of the periodic system for powers of two"
• about eight chemistry-based differences between Ti-V-Cr and Mn, including where Mn shows more similarities to Fe-Co-Ni, for example:
  • divalent Ti, V, Cr cations are all powerful reducing agents, Cr being one of the most powerful known; divalent Mn, Fe, Co, Ni are either very mild reducing agents as divalent Mn or Fe, or have almost no reducing power in the case of divalent Co or Ni;
  • metal titanates, vanadates and chromates are stable in alkaline solution and are unstable in the presence of acid whereas permanganates are more stable in acid than alkali; their oxidizing power is also widely different.

I can further add:

• Mn, Fe, and Co, and to some extent Ni, occupy the "hydrogen gap" among the 3d metals, having no or little proclivity for binary hydride formation
• the +2 and +3 oxidation states predominate among the Mn-Fe-Co-Ni tetrad (+3 not so much for Mn)
• in old chemistry, Mn, Fe, Co, and Ni represented the "iron group" whereas Cr, Mo, W, and U belonged to the "chromium group": Struthers J 1893, Chemistry and physics: A manual for students and practitioners, Lea Brothers & Co., Philadelphia, pp. 79, 123
• Tc forms a continuous series of solid solutions with Re, Ru, and Os

Moving forward precisely 100 years, Rayner-Canham (2018) made the following observations:

• Conventional classification systems for the transition metals each have one flaw: "They organise the TM largely according to one strategy and they define the trends according to that organisation. Thus, linkages, relationships, patterns, or similarities outside of that framework are ignored."
• There are two oxide series of the form MnO and Mn3O4 which encompass Mn through Ni. Here the division is not clear cut since there are also the series Mn2O3 for Ti-Cr and Fe; and MnO2 for Ti to Cr.
• Under normal condition of aqueous chemistry, Mn favours the +2 state and its species match well with those of the following 3d member, Fe.

  Rayner-Canham G 2018, "Organizing the transition metals" [a chapter in] in E Scerri & G Restrepo, Mendeleev to Oganesson: A multidisciplinary perspective on the periodic table, Oxford University Press, Oxford, pp. 195–205

I've also attached a modern interpretation of von Bichowsky’s table. It's curious how there are eight metals (Fe aside) capable of, or thought to be capable of, achieving +8. I am not sure that a table of this kind with Lu in group 3 is possible, without upsetting its symmetry."

Black & Conant's Periodic Classification Of The Elements

From N.H. Black NH & J.B. Conant's Practical Chemistry: Fundamental Facts and Applications to Modern Life, MacMillan, New York (1920)

Eric Scerri, who provided this formulation writes (personal communication):

"Notice conspicuous absence of H. And, Conant was the person who gave Kuhn his first start in the history of science at Harvard."

René Vernon tells us that Conant and his coauthor write:

"The position of H in the system has been a matter of some discussion, but it is not of much consequence. It seems to be rather an odd element. Perhaps the best place for it is in group IA as it forms a positive ion." (p. 350)

Sommerfeld's Electon Filling Diagram

Arnold Sommerfeld diagram appears in an issue of Memoirs and Proceedings of the manchester Literary and Philosophical Society for 1925-26. volume 70, p. 141-151.

Eric Scerri writes:

"The electron groupings are not exactly the same as what is believed to exist today but it amounts to the same order of filling. For example p orbitals were thought to consist of two groups of 2 and 4 electrons, rather than 2, 2, 2 as believed today. Similarly d orbitals were thought to be formed of two groups of 4 and 6 electrons. With that in mind you will see that Sommerfeld was the first to propose an aufbau filling system: The occupation of 4s before 3d or as represented here the 2 electrons in orbit 11 followed by the 4 and 6 from orbits 3,s and 3,3.

"Sommerfeld does indicate sub-shells. They are just not the same groupings as the current ones. For example 2,1 and 2,2 indicates subshells within the 2nd main shell. Similarly the 3rd shell is presented as 3,2 and 3,3. The totals are of course the same, namely 6 for what we now call p orbitals and 10 for what we call d orbitals. All this came before the discovery of the 4th or spin quantum number. This is in keeping with Bohr's original assignment of shells and sub-shells.

"The discovery of sub-structure to electron shells was not an 'all or nothing' development, but a gradual and almost organic evolution."

Eric has a new book out – A Tale of Seven Scientists and a New Philosophy of Science – in which the gradual evolution of electronic structure involving Bohr, Sommerfeld, Bury, Main Smith, Pauli and others is traced out.

Courtines' Model of the Periodic Table or Periodic Classification

Published in J. Chem. Ed., 2, 2, 107-109 in 1925 by M. Courtines of the Laboratory of Experimental Physics, College of France, Paris.

Q&Q write:

"The unfolded tower arrangement appears much like a modernised Chauvierre chart cut on a line between Ni and Cu, Cu, with the right part fitted to the left in order of increasing atomic numbers. The rare-earth elements, however, are placed on a novel accordion-like folded strip with ends made secure just below Xt and between Ba and Hf. The author describes in detail the method of folding the chart into a tower-like cylindrical model. H is folded back to show its lack of relationship other groups of elements. In the space for each symbol, electron arrangements and isotopes are also enumerated."

This table is from the book "Practical Inorganic Chemistry" Publisher EH Riesenfeld Labor, Barcelona (1950). It is a reprint of the second edition (1943) which in turn is a translation of a German edition, its seventh edition in 1928. This suggests that Riesenfeld is himself the author of it.

It is a pre-Seaborg table in the sense that the actinides are known throughout the period July. It also does not include the Tc since it was discovered in 1937. These facts support the dating of the table. But the most interesting thing about it is that to make the separation between subgroups and major groups Be cut after the first period and after the Al in the second. Which leaves isolated in group B without any element 2b below it:

Nekrasov Periodic Table

From here, using Google Translate:

The shape of the table is presented by Bohr effect of considering the properties of the elements as simple substances and for reactions to occur with the intervention of such substances. But for the study of compounds and reactions that occur between them, the key factor is the electron configurations of atoms in states of valence to them on the given compounds.

It follows that a more complete picture of the periodic table would be when you take into account the peculiarities of atoms in both its neutral state and in all its particular valence states. This is the proposal of Boris Nekrasov, a member of the Academy of Sciences in Moscow.

Nekrasov distinguishes three types of analogies between elements Total analogs are those in which the analogy is shown in all its valence, all analogs compared to the valence valences except for the group corresponding to the number that can be called characteristic and analogous to the valence characteristic .

Thus, in the table shown here distinguish the elements entirely analogous joined by continuous lines, such as Na and K.

Those analogies in all except the characteristic valences joined by dotted lines. This is the case of Na and Cu in both cases if you lose an electron (valence feature) your setup is different. In the first case is 8 (1s2, 2P6) and the second 18 (3s2, 3p6, 3d10).

Lastly presenting exclusively analogies valence are connected with dashed lines. This is the case both S and Cr +6 elements have their valence electron configuration similar in the last layer 8 (2s2, 2p6) for the S and 8 (3s2, 3p6) for Cr.

Paneth's Table

Published by Paneth in 1942 in an article in Nature in which he suggests that newly discovered elements such as Z = 43 should be given names by their discoverers. The other highlighted elements (below) had also not yet been named.

Element 43 had been discovered 9 years earlier but had not been given an official name because there was reluctance to consider synthetic elements on the same footing as naturally occurring ones. This changed as a result of Paneth's article.

Russian Periodic Table(s)

Eric Scerri writes:

"The periodic tables [below], and data, are from some Russian books given to me by the late Ray Hefferlin, when I visited him a few years ago in Tennessee. Sorry, I can't give any source details as the inserts got separated from the book."

The captions say: "Fig. XVII. Block-type periodic table" and "U.L.Kulakov, Classification of the chemical elements on the new background".

Looking at the graphics style, we are guessing they date from the mid-1970s (MRL)

Elsevier's Periodic Table of the Elements

Prepared by P. Lof is Elsevier's Periodic Table of the Elements.

This educational wall chart features the periodic table of the elements supported by a wealth of chemical, physical, thermodynamical, geochemical and radiochemical data laid down in numerous colourful graphs, plots, figures and tables. The most important chemical and physical properties of the elements can be found - without turning a page.

All properties are presented in the form of tables or graphs. More than 40 properties are given, ranging from melting point and heat capacity to atomic radius, nuclear spin, electrical resistivity and abundance in the solar system. Sixteen of the most important properties are colour coded, so that they may be followed through the periodic system at a glance. Twelve properties have been selected to illustrate periodicity, while separate plots illustrate the relation between properties. In addition, there are special sections dealing with units, fundamental constants and particles, radioisotopes, the Aufbau principle, etc. All data on the chart are fully referenced, and S.I. units are used throughout.

Designed specifically for university and college undergraduates and high school students, "Elsevier's Periodic Table of the Elements" will also be of practical value to professionals in the fields of fundamental and applied physical sciences and technology. The wall chart is ideally suited for self-study and may be used as a complementary reference for textbook study and exam preparation.

Eric Scerri's Triad Periodic Table

Eric Scerri says, "I have recently developed a new periodic table with some very nice features. I am now shifting my allegiance from the left-step table to this one."

• New design based on the fundamental nature of triads, and on atomic number triads in particular.
• H,F,Cl is a new perfect atomic number triad not featured in the usual medium-long form table. There are also many chemical arguments for placing H among the halogens rather than the alkalis.
• Note the regularity regarding period lengths. 8, 8, 18, 18, 32, 32 ...
• All period lengths repeat without fail, unlike in the medium-long form.
• Also note the bi-lateral symmetry assuming the rare earths are given as a footnote.

Periodic Arch of The Elements

Cynthia K. Whitney of Galilean Electrodynamics writes: "In his paper Explaining the periodic table, and the role of chemical triad, Eric Scerri mentioned the existence of at least four different candidate places for Hydrogen: Group 1 (alkali metals - Lithium, etc.), Group 17 (halogens - Fluorine, etc.), Group 14 (Carbon, etc.), or off the Periodic Table entirely, because it is so odd! The four-fold multiplicity (and maybe more) of candidate places for Hydrogen triggered in me the following thought: the excessive multiplicity of candidate places may have to do with the rectangular nature of the Periodic Tables under consideration there."

Before & After Mendeleev: Periodic Table Videos

Two videos by the Chemical Heritage Foundation:

• Part 1 Before Mendeleev (17min) covers the events leading up to Mendeleev's invention of the periodic table, including the work of several precursors such as de Chancourtois, Newlands, Odling, Hinrichs, and Meyer.
  
  
• Part 2 Mendeleeve & Beyond (20 min). The second part covers Mendeleev's working out of his periodic system and the work of his successors, as well as some interesting questions such as whether the periodic table can be entirely deduced from quantum mechanics and the mystery of the Knight's Move pattern of properties.

The videos feature interviews with Dr. Eric Scerri of UCLA, with added narration, animations, illustrations, photos, captions, etc. by David V. Black as well as publication artwork and notes by Edward G. Mazurs.

Science Museum Lockers

From Kotaku:

While visiting the Nagoya City Science Museum, Twitter user Kantaku noticed something very cool, the coin lockers.

The name of each element is written below each symbol in Japanese, allowing visitors to store their belongings in Helium, Calcium, Oxygen, Potassium and more.

The number of each locker corresponds to the element. So, locker 21 is Scandium as it's the twenty-first element on the periodic table. Locker 3? It's Lithium, like it is on the periodic table, and so on. Dibs on Krypton!

Homenatge Als Elements

From Eugènia Balcells' blog (and translated using Google Translate):

TRIBUTE TO THE ELEMENTS was born as a counterpoint to the video-installation Eugènia Balcells often, a film without end where the trace elements that each emit light merges with the other and forming a true metaphor for origin of the universe.

Coinciding with the International Year of Chemistry, TRIBUTE TO THE ELEMENTS has been published in two formats: a poster in which each element is represented by its chemical symbol and its own emission spectrum and a version where each element, printed separately, part of a collection that can be stored as such or are available as a mural on a temporary or permanent exhibition space, as presented in the exposure:

Eric Scerri's Lecture on The Periodic Table

A lecture by Eric Scerri at the Oscar Peterson auditorium of Concordia University, in Montreal.

The topic is the history and iconic nature of the Periodic Table, in high quality video, about one hour:

Srivaths–Labarca Periodic Table

This is an improved version of the Zigzag Periodic Table (2012). In this new arrangement the main criteria proposed to settle the placement of the elements hydrogen and helium has been taken into account: electronic configurations, the number of electrons needed to fill the outer-shell, chemical behavior, and triads of atomic number.

This is a new categorial criterion recently proposed by Eric Scerri, according to which hydrogen and helium form part of the triads H(1), F(9), Cl(17) and He(2), Ne(10), Ar(18), respectively. Thus, hydrogen preserves its place between alkali metals and halogen while helium is now in between noble gases and alkaline earth elements.

This periodic table allows visualizing easily the relationships of hydrogen and of helium with the different criteria, avoiding drawing lines to see them in contrast to other similar periodic systems.

But the sleek, shiny iPhone is far, far removed from the rocks pulled out of this giant hole, which looks like a deep crater on the moon. Inside the rocks from this mine are rare-earth minerals, crucial ingredients for iPhones, as well as wind turbines, hybrid cars, and night-vision goggles. Minerals such as neodymium are used in magnets that make speakers vibrate to create sound. Europium is a phosphor that creates a bright red on an iPhone screen.

Three Different Long-Form, or 32-Column, Periodic Tables

From an article by Eric Scerri in the IUPAC magazine, Chemistry International, in which three different long-form, or 32-column, periodic tables with differences highlighted.

• Top: Version with group 3 consisting of Sc, Y, Lu, and Lr.
• Middle: Version with group 3 consisting of Sc, Y, La, Ac. The sequence of increasing atomic number is anomalous with this assignment of elements to group 3, e.g., Lu (71), La (57), Hf (72).
• Bottom: Third option for incorporating the f-block elements into a long-form table. This version adheres to increasing order of atomic number from left to right in all periods, while grouping together Sc, Y, La and Ac but at the expense of breaking-up the d-block into two highly uneven portions :

London, Periodic Table of

Like the Tube Map, the Periodic Table is an endlessly fascinating thing. Over the years, the format has been adapted to all kinds of schemes. A few years ago, we tried to make sense of London in this way, by arranging important facets of the capital into rows and columns. It's been a while, so we've now updated it, with a few changed entries and a general tidy up. Can you work out the identity of each London 'element'? Can you spot hidden patterns and trends? Can you suggest improvements?

4D Stowe-Janet-Scerri Periodic Table

By Jgmoxness who writes:

"I've replaced the standard periodic table in the 7th "Chemistry Pane" of my E8 visualizer with a 2D/3D/4D Stowe-Janet-Scerri version of the Periodic Table.

"Interestingly, it has 120 elements, which is the number of vertices in the 600 Cell or the positive half of the 240 E8 roots. It is integrated into VisibLie_E8 so clicking on an element adds that particular atomic number's E8 group vertex number to the 3rd E8 visualizer pane.

Periodic Pyramid

A Periodic Pyramid by Jennifer N. Hennigan and W. Tandy Grubbs * Department of Chemistry, Stetson University, DeLand, Florida 32723, United States

J. Chem. Educ., 2013, 90 (8), pp 1003-1008 DOI: 10.1021/ed3007567 Publication Date (Web): June 21, 2013

The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a maximum of 2, 8, 18, and 32 electrons can occupy the shells identified by the principle quantum numbers n = 1, 2, 3, and 4, respectively. The numbers 2, 8, 18, and 32 are shown in this work to be related to the triangular numbers from mathematical number theory. The relationship to the triangular numbers, in turn, suggests an alternate method for arranging elements in terms of periodicity. The resulting three-dimensional "periodic pyramid" is highly symmetric in shape. Just as is true in the modern periodic table, each layer of the periodic pyramid can be separated into shell and subshell contributions. Examining the pyramid's structure is arguably a pedagogically useful activity for college-level introductory or physical chemistry students, as it provides an opportunity to further ponder the shell model of the atom and the origins of periodicity. The connections to number theory are used to show that the outermost subshell of a given shell contains (2n - 1) orbitals.

Bernard Periodic Spiral

The Bernard Periodic Spiral of the Elements (BPSE), depicts a novel rendition of the Periodic Table that replaces the flat rectangular format with a continuous unidirectional spiral that maintains all the properties of Group and Period formation.

Comparisons may be made with similar models spanning the last three decades of the 20th century (Alexander, 1971; Mazurs, 1974; & Kaufman, 1999).

In the chart form, this new rendition is referred to as the Elliptical Periodic Chart of the Elements. In the three-dimensional form, the model resembles a Christmas tree in shape with the 7 Periods represented as circular platforms situated at various levels with the elements placed appropriately at the outer edges of each of these platforms as a Period builds up. The elements may be represented as spherical objects or flat discs with radii proportionate to atomic radii (or reasonable approximations). Color schemes accentuate the four different Blocks of elements: the s-Block (green), the p-Block (blue, with the exception that the last Group is red signifying the end of a Period), d-Block (orange), and the f-Block (yellow). The grey section, called the Group-Period Interchange, is where the end of a particular Period connects to the beginning of the next Period, and, at the same time, transitions from Group 18 to Group 1.

Labarca & Zambon's Formulation

Labarca & Zambon's new representation of the periodic system.

A reconceptualization of the element concept as a basis for a new representation of the periodic system, Martín Labarca and Alfio Zambon, Educ. Quím., 24(1), 63-70, 2013.

"The aim of this paper is to propose a new conceptualization of the term 'element' as the basis for a new representation of the periodic system. For this purpose we begin by recalling the dual sense of the concept of element. Next, we develop the 'limits isotopes' argument which is the basis of the new periodic chart. This task leads us both to reconceptualize the notion of element and to characterize the term 'basic substance'. In turn, the argument is used to face the epistemological problem with hydrogen and helium in the periodic table. Finally, the Döbereiner's triads are used to calculate atomic masses in three periodic charts: the medium-long-form, the modified 'left-step' proposed by Scerri, and the proposed in this work. Evaluation results allows us to stand out the fruitful predictive power of our periodic system.

"The 46 blocks of elements are ordered vertically by the increasing number of neutrons of the lighter isotope (primary criterion) and, horizontally, by the increasing atomic number (secondary criterion). The subscript represents the value of L - Z and the superscript the value of Z."

Zambon's Periodic Table Based on Triads

Alfio Zambon – Universidad Nacional de la Patagonia

1. Introduction

In the last decades, the notion of triad has been recovered by Eric Scerri, who suggested it as a possible categorical criterion to represent chemical periodicity. In particular, he reformulates the notion of triad in terms of atomic number instead of atomic weights and, in this way, the value of the intermediate term of the triad is the exact average of the values of the two extremes. The author notes that the attempt of finding new triads is very important since this relation is based exclusively on the atomic number, that is, the only feature of the elements considered as basic substances. In this work, I will follow Scerri's general proposal.

Mystery of Matter: Search for the Elements

The Mystery of Matter: Search for the Elements is a multimedia project about one of the great adventures in the history of science: the long (and continuing) quest to understand what the world is made of – to identify, understand and organize the basic building blocks of matter. In a nutshell, the project is about the human story behind the Periodic Table of the Elements.

The centerpiece of the project is a three-hour series that premieres Aug. 19, 2015 on PBS. The Mystery of Matter introduces viewers to some of history's most extraordinary scientists:

• Joseph Priestley and Antoine Lavoisier, whose discovery of oxygen – and radical interpretation of it – led to the modern science of chemistry
• Humphry Davy, who made electricity a powerful new tool in the search for elements
• Dmitri Mendeleev, whose Periodic Table brought order to the growing gaggle of elements
• Marie Curie, whose groundbreaking research on radioactivity cracked open a window into the atom
• Henry Moseley, whose investigation of atomic number redefined the Periodic Table
• Glenn Seaborg, whose discovery of plutonium opened up a whole new realm of elements, still being explored today.

The Mystery of Matter will show not only what these scientific explorers discovered but also how, using actors to reveal the creative process through the scientists' own words, and conveying their landmark discoveries through re-enactments shot with replicas of their original lab equipment. Knitting these strands together into a coherent, compelling whole is host Michael Emerson, a two-time Emmy Award-winning actor best known for his roles on Lost and Person of Interest. Eric Scerri appears as the expert.

New Rendering of ADOMAH Periodic Table

From Valery Tsimmerman, of the PerfectPeriodicTable.com and the ADOMAH Periodic Table:

"I received email from Dr. Marcus Wolf who is a chemist, working on renewable energy and electrochemical storage in Germany, near Nuremberg. He also lectures at Georg Simon Ohm, Technische Hochschule Nürnberg. Attached to his email was new version of ADOMAH Periodic Table that he created. In this new rendering he is using Jensen's Valence Manifold (VM)."

This is what Dr. Marcus Wolf wrote:

"The first one to come up with the idea of using a valence manifold VM = [e + v] as a label for the groups, was Will B. Jensen. He derived it from the very early attempts of Richard Abegg, who, at around 1904, brought up the hypothesis of 'main- and counter-valences', derived from the observable behavior of elements and their compounds in electrochemical experiments. Eric Scerri is citing Jensen in his latest book, in the chapter about Richard Abegg. But Jensen's proper article from 1983 or so is far more detailed and in his later publications he then introduces the valence manifold concept. Last weekend I accidentally observed another consistency between the G-values and their ordering and the valence electron counts, e. If you fix the e value of the starting group in a given l-block as e(initial), you could generate every G-number of a given group by adding the valence vacancy count, v, to it:

G = e(initial) + v.

"That is another hint for the consistency of the VM labelling concept."

Kurushkin's 32-Column Periodic Table & Left-step Periodic Table United

Dr Mikhail V. Kurushkin, 32-column Periodic Table & Left-step Periodic Table United: https://bernalinstitute.com/events/bernal-seminar-by-dr-mikhail-v-kurushkin-itmo-universityrussia/

ABSTRACT
The pursuit of optimal representation of the Periodic Table has been a central topic of interest for chemists, physicists, philosophers and historians of science for decades (Leigh, 2009; Scerri, 2009). Should the Periodic Table of Chemical Elements first and foremost serve the needs of chemists as implied by its name? Or should it start from considerations of before quantum mechanics and thus be more appealing to physicists (Scerri, 2010, 2012b)? Is there a representation which overcomes this problem? The Periodic Table is from a fundamental point of view a graphic representation of periodicity as a phenomenon of nature. While the 32-column Periodic Table, popularized by Glenn T. Seaborg, is considered by chemists the most scientifically correct representation (Scerri, 2012a), physicists apparently prefer the Left-step Periodic Table above all (Scerri, 2005; Stewart, 2010). Alternatively, it is suggested that a rigorously fundamental representation of periodicity could only take the form of a spiral as, evidently, the abrupt periods of 2-D Periodic Tables contradict the gradual increase of atomic number, and the spiral representation reconciles this debate (Imyanitov, 2016). An optimal representation is eagerly sought after both for the needs of philosophy of chemistry and chemical education as their never-ending dialogue secures a thorough methodology of chemistry. The aim of the present work is to show that the 32-column Periodic Table and the Left-step Periodic Table can co-exist in mutual tolerance in a form of what Philip Stewart has already called Kurushkin’s Periodic Table (Kurushkin, 2017), Figure 1 below.

René Vernon writes:

"Kurushkin reminds us that the Janet left step table (with Sc-Y-Lu-Lr, and He over Be), and the version of the table with the s-elements on the right (also with Sc-Y-Lu-Lr, and He over Be) are interchangeable.

"For an earlier paywall version which includes a short video see:

"Kurushkin’s interchangeable approach extends to tables with group 3 as either Sc-Y-La-Ac or Sc-Y-Lu-Lr. See Vernon's Yin Yang of The Periodic Table https://www.meta-synthesis.com/webbook/35_pt/pt_database.php?PT_id=1252"

Group 3 of The Periodic Table

There are several ways in which the 'common/modern medium form' periodic table are shown with respect to the Group 3 elements and how the f-block is shown. Indeed, there is even some dispute about which elements constitute Group 3. There are three general approaches to showing Group 3:

• Sc, Y, La, Ac
• Sc, Y than a gap for the lanthanides & a gap for the actinides
• Sc, Y, Lu, Lr

(See Scerri's take and Thyssen's view on this matter.)

So, which one of the three options is 'better'?

The general feeling amongst the knowledgeable is that leaving a gap is not an option, so it comes down to:

Sc, Y, La, Ac     vs.     Sc, Y, Lu, Lr

René Vernon has looked as the properties of the potential Group 3 elements, including: densities, 1st ionisation energies, ionic radii, 3rd ionisation energies, melting points & electron affinity:

Figure 1 shows that a Z plot of the density values for Sc, Y, La, Lu Ac and Lr follows a smooth trendline.

Figure 2 shows that a Z plot of the first ionization energy values follows a smooth trendline.

Figure 3 shows that a Z plot of the 6-coordinate ionic radii for the subject elements bifurcates after Y into an -La-Ac tranche (R2 = 0.99) and a -Lu-Lr branch (0.61). The trendline for -La-Ac is smoother.

Figure 4 shows a Z plot of 3rd ionisation energy values bifurcating after Y into a -Lu-Lr tranche (R2 = 0.83) and a -La-Ac branch (0.98). The trendline for -La-Ac is smoother.

Figure 5 shows that a Z plot of the melting points bifurcates after Y into an -Lu-Lr (R2 = 0.72) tranche and a -La-Ac (0.71) branch. While the fit values for the two options are comparable, -Lu-Lr is preferred since Y and La show a greater departure from trend.

Figure 6 has a Z plot of electron affinity values bifurcating after Y into an -La-Ac tranche (R2 = 0.85) and a -Lu-Lr branch (0.99).[iii] The trendline supports Lu-Lr. The trend-lines by themselves are inconclusive: two show no difference; two support -La-Ac; two support -Lu-Lr.

Upon reviewing the data, René's comment is that: "The net result is that the two options seem inseparable" and he proposes that IUPAC adopt the following periodic table numbering system:

UCLA Periodic Table (Proposed)

Eric Scerri writes:

During an office hour here at UCLA with a couple of students – Annelise Gazale & Chidinma Onyeonwu – we came up with a 'new periodic table'.

The basis of it is related to a point you frequently make against the Left Step formulation, namely that it messes up trends in atomic radius etc.

So how about this: Traditionally on the right side of the table elements become less reactive as we move down, but on the right side of the table elements become more reactive as we move down. Consequently, the noble gases are anomalous in the way they usually sit since they become more reactive as we move down the table.

Ergo: Move the noble gases to the left edge of the table. (Yes, this has been done before of course but not for this reason.)

Möbius-Escher Periodic Table

A comment article in Nature by Prof. Eric Scerri about quantum mechanics and the periodic table:

"Can quantum ideas explain chemistry's greatest icon? Simplistic assumptions about the periodic table lead us astray.

"Such has been the scientific and cultural impact of Dmitri Mendeleev's periodic table of the elements that many people assume it is essentially complete. [But] in its 150th year, can researchers simply raise a toast to the table's many dividends, and occasionally incorporate another heavy synthetic element?

"No – this invaluable compilation is still not settled. The placements of certain elements, even hydrogen and helium, are debated."

Schaltenbrand's Helical Gathering of the Elements

From the RSC Website:

"A glistering, shining spiral made of silver, gold, platinum, palladium and a diamond forms the show-stopping apex of the tribute from the University of Cambridge's St Catharine's college to the International Year of the Periodic Table.

"Commissioned to match George Schaltenbrand's 1920 design for a helical gathering of the elements – albeit extended to all 118 current elements – and signed by Yuri Oganessian, it is almost certainly the most expensive periodic table in the world."

Poliakoff's Inverted Periodic Table

From Nature Chemistry. Martyn Poliakoff et al write:

"The inverted periodic table is obtained by rotating the conventional one by 180° about a horizontal axis.

"a, The lighter elements are now at the bottom and the filling of the electron shells occurs upwards. Just like the traditional representation, many properties (for example, atomic number) increase across the table as one proceeds from left to right, but in the inverted version, the same properties now increase as one moves from the bottom to the top, which is the way that most graphs are plotted. Also like the conventional table, the lanthanides and actinides still sit uncomfortably in an isolated block.

"b, In principle, this could be overcome by inverting the 'long form' of the table but, like the conventional long form, it is probably too elongated to be very useful to most chemists."

What Is A Chemical Element?

A Collection of Essays by Chemists, Philosophers, Historians, and Educators Edited by Eric Scerri and Elena Ghibaudi published by Oxford University Press

• A collection of 14 edited papers from historians of chemistry, philosophers of chemistry, and chemists with epistemological and educational concerns
• Contains educational debates concerning how to teach and present the concept of elements
• Provides a beneficial, scholarly, unique, and understandable overview of the current debate on the chemical elemen.

The concept of a chemical element is foundational within the field of chemistry, but there is wide disagreement over its definition. Even the International Union for Pure and Applied Chemistry (IUPAC) claims two distinct definitions: a species of atoms versus one which identifies chemical elements with the simple substances bearing their names. The double definition of elements proposed by the International Union for Pure and Applied Chemistry contrasts an abstract meaning and an operational one. Nevertheless, the philosophical aspects of this notion are not fully captured by the IUPAC definitions, despite the fact that they were crucial for the construction of the Periodic Table. Although rich scientific literature on the element and the periodic table exists as well as a recent growth in the philosophy of chemistry, scholars are still searching for a definitive answer to this important question: What is an element?

Eric Scerri and Elena Ghibaudi have teamed up to assemble a group of scholars to provide readers an overview of the current state of the debate on chemical elements from epistemological, historical, and educational perspectives. What Is A Chemical Element? fills a gap for the benefit of the whole chemistry community-experimental researchers, philosophers, chemistry educators, and anyone looking to learn more about the elements of the periodic table.

Vernon's Periodic Table showing the Idealized Solid-State Electron Configurations of the Elements

René Vernon writes:

"I've attached a periodic table showing the solid-state electron configurations of the elements. Among other things, it provides a first order explanation as to why elements such as Ln (etc.) like the +3 oxidation state.

"The table includes two versions of the f-block, the first starting with La-Ac; the second with Ce-Th. The table with the first f-block version has 24 anomalies [with respect to Madelung's rule]; the table with the second f-block version has 10 anomalies.

"In the case of the Sc-Y-La-Ac form, I wonder if such a solid-state table is more relevant these days than a table based on gas phase configurations, which has about 20 anomalous configurations.

"Partly we use gas phase configurations since, as Eric Scerri mentioned to me elsewhere, configurations were first obtained (~100 years ago?) from spectroscopy, and this field primarily deals with gas phase atoms. That said, are gas phase configurations still so relevant these days – for this purpose – given the importance of solid-state physics?

"I've never been able to find a periodic table of solid-state electron configurations. Perhaps that has something to do with it? Then again, surely I'm not the first person to have drawn one of these?"

150 Years of the Periodic Table

Based on the ACS 2019 symposium "150 Years of the Periodic Table". Provides an overview of how the periodic table has evolved over the past 150 years Written by leading experts in the field: Editors: Giunta, Carmen, Mainz, Vera V., Girolami, Gregory S. (Eds.)

This book provides an overview of the origins and evolution of the periodic system from its prehistory to the latest synthetic elements and possible future additions. The periodic system of the elements first emerged as a comprehensive classificatory and predictive tool for chemistry during the 1860s. Its subsequent embodiment in various versions has made it one of the most recognizable icons of science.

Based primarily on a symposium titled "150 Years of the Periodic Table" and held at the August 2019 national meeting of the American Chemical Society, this book describes the origins of the periodic law, developments that led to its acceptance, chemical families that the system struggled to accommodate, extension of the periodic system to include synthetic elements, and various cultural aspects of the system that were celebrated during the International Year of the Periodic Table.

World's Largest Periodic Table Created on ECU's Science Building

From architectureanddesign.com.au:

"The new science building at Edith Cowen University (ECU), Joondalup Campus in Perth stands out for its striking façade, which features the world's largest periodic table. The thoughtful design by Silver Thomas Hanley Architects responded to the brief to deliver a bold and sophisticated architectural statement in the urban setting. The façade featuring the periodic table celebrates the building's purpose as a centre of scientific research and learning. Based on the university vice chancellor Professor Steve Chapman's idea, the periodic table is an enormous 662 square metres, spanning the entire front façade of the building."

Largest Periodic Table in Eurasia Created in Dubna

From The Times of India:

"The largest [PT] in Eurasia, the Periodic Table of Mendeleev opened in Dubna near Moscow. The event is timed to coincide with the 65th anniversary of the Joint Institute for Nuclear Research located here and the city itself. It is noteworthy that it is at JINR, in the Laboratory of Nuclear Reactions. G N Flyorov under the guidance of Academician of the Russian Academy of Sciences Yuri Oganesyan, all known to date superheavy elements were obtained – from 113th to 118th (the latter is even named after the scientist – 'Oganeson Og'). Oganesyan is the second scientist in the world, after whom a new element of the Periodic Table was named during his lifetime (the first was the American scientist Glenn Theodore Seaborg)."

Meyer or Mendeleev: Who created the periodic table?

Vernon's Yin Yang of The Periodic Table

René Vernon writes:

"I was prompted to [develop] this item after reading Eric Scerri's open access article: In Praise of Triads. The nub of Eric’s article is to argue for the LST on the grounds of triad regularity, first-row-anomaly regularity, and consistency with QM.

"It occurs to me that efforts to introduce more regularity to the PT invariably introduce new irregularities elsewhere. For example, as far as triad regularity goes, the left step table (LST) with He over Be introduces its own anomaly in that no element in period 1 (H, He) is part of a triad whereas this is not the case for all periods thereafter. In contrast, all periods of the traditional table have at least one element that is part of a triad.

"As far as QM goes, this tells us that there is a theoretical regularity to the PT. This regularity can be used to inform e.g. the LST, ADOMAH or Julio’s binodes. But such depictions do not reflect the factual relationships we see amongst the chemistry of the elements as well as is the case for the conventional form. A most obvious example is that the LST, while being more consistent with QM, disrupts the bottom-left to top-right trend in metallic to nonmetallic character seen in conventional tables.

(I must caveat that I'm referring to the chemistry of the elements in conditions regularly occurring on Earth. For example, it has been reported that under sufficiently high pressures the elements change their EN and electron configurations. If so, this suggests a need for a different table at high pressure.)

At this point, the chemistry educators enter the picture. They move the s-block to left. Helium is relocated over Ne on the basis of its nobility. (This could change if a few compounds of He were to be synthesized). Somewhat similarly, La was discovered well before Lu, so it ended up under Y, and most folks see no good reason to replace La with Lu. Sure, in the 32-column form, the result is a split d-block but the infrequency with which the 32-column form appears is such that most people are not bothered. The result is the conventional table.

Philosophically, while the n+l based LST might represent the most general form of table, the conventional table appears to currently represent the most pragmatic derivation for chemists and chemistry educators.

Since the PT is classification rather than theory, and there will thus always be hard cases at the boundaries, there will invariably be minor variations in the depiction of the conventional table with respect to e.g. the placement of H, the composition of group 3, or the length of the f block.

And there will always be tables such as MR that focus on particular perspectives of relationships among the the elements.

I’ve tried to sketch what's going in the attached image:"

Ramsay-Sommerfeld Periodic Table

John Marks has updated Scerri's 2006 Triad formulation. Marks writes:

"[This is] an expansion of Scerri´s 2006 triad formulation, but brings the lanthanides & actinides in from the cold. It is lso modelled on the way IUPAC constructed its 18-group PT (but with traditional group numbering), that is to say, the total of 22 groups is simply IUPAC's 18 plus the four extra f-groups. I am not sure if this counts as a "medium" or a "long" form.

"If this PT needs a name, it would be the Ramsay-Sommerfeld PT. It has Ramsay´s 1915 arrangement for H (copied by Eric Scerri in 2006) and Sommerfeld's "greater" and "lesser" periods (1916) in green and yellow respectively. It solves the 'exile' of the f-blocks without making it too unwieldy (22 instead of 32 groups). The yellow (transition series) are Sommerfeld's 'A' subgroups and the green (rare earth series) are Sommerfeld's 'B' subgroups."
