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."

Pauling Spheron Periodic Table

The Pauling Spheron Periodic Table, can be found at APM Periodic Tables.

Linus Pauling was a brilliant physicist who tended to think outside the mainstream. One of his many contributions to science was his spheron model for the nucleus. The word "spheron" does not mean the nucleus is spherical (although it may be), it refers to Pauling's idea that clusters might form in the nucleus. For example, a nucleus may contain a stable helium nucleus within a larger uranium nucleus. Thus, when uranium decays, it releases a helium atom. Other elements, such as oxygen, may also cluster within larger elements. This makes sense since certain atoms like helium and oxygen are more strongly bound than other elements:

Harrison Spiral Periodic Table

This spiral, inspired by Stewart's Chemical Galaxy, is based on the modern periodic table with the elements strictly arranged in the increasing order of their atomic number and in accordance with their electron configurations.

The spiral separates the elements into the eight dominant 'A' groups of normal elements, and the eight corresponding 'B' subgroups of transitional and inner transitional elements, which have been incorporated as the inner spiral. The organisation of the elements closely follows H.G. Deming's 1923 Periodic Table where A B numeration was first utilized to correspond the characteristic oxides of the 'B' groups to those of the 'A' groups. The result of this design places Group VIII, the triads Fe, Co, Ni, etc. as a subgroup of Group 0 (or 18 Helium Group) which conflicts with some modern periodic tables, though broadly agrees with Deming's original proposal (VIIIA and VIIIB).

Hydrogen, which generally cannot be considered as part of any group, has been placed with the Fluorine group VII which appears its natural place in the spiral. Common names have been used where practicable to make the table more educational and reader-friendly. Element symbols have been included in the expanded poster of this table.

Upper Limit in Mendeleev's Periodic Table - Element No.155

This book (PDF), by Albert Khazan, represents a result of many-year theoretical research, which manifested hyperbolic law in Mendeleev's Periodic Table.

According to [Khazan's] law, an upper limit (heaviest element) exists in Mendeleev's Table, whose atomic mass is 411.66 and No.155. It is shown that the heaviest element No.155 can be a reference point in nuclear reactions. Due to symmetry of the hyperbolic law, the necessity of the Table of Anti-Elements, consisting of anti-substance, has been predicted. This manifests that the found hyperbolic law is universal, and the Periodic Table is common for elements and anti-elements.

Newlands Revisited – Poster

At the beginning of last year (Meyers, 2009), a IUPAC editorial offered "something old, something new, something borrowed and something blue".

Marks and Marks 2010 (M&M) preserves the old subgroups (Newlands' columns) that were a feature of all short forms, although M&M would then have been described as a 'medium form' (14 groups) in contrast to Mendeleyev's 'short form' (8 groups) or Werner's 'long form' (32 groups). M&M naturally continues the grouping of the lanthanoids/actinoids whose initial four groups were also included in 'short form' tables.

The logic of the arrangement of the s-elements is a new feature. It recognizes the chemical subgroups of hydrogen, viz. the alkali metals and the halogens, and of helium, viz. the alkaline earth metals and the inert gases. It is interesting to note that subgroups differ chemically from each other inversely as the azimuth, i.e. Li:F > Ca:Zn > La:Lu.

The whole idea is, of course, borrowed from Newlands. The group numbers are borrowed from valency but also from electronic structure in that the number of s, p, d, or f subgroups corresponds to the Pauli maximum for each. Finally, the mnemonic reflects that most elementary introduction to chemistry: alkalis turn Litmus blue.

From this start, the p-bloc is red, the transition elements yellow and the "rare earth" elements green, as argued in the M&M paper. The numbering of groups I - XIV is unambiguous, it is less than IUPAC's arbitrary 18 groups, it preserves subgroups and satisfactorily accommodates hydrogen and the lanthanoids/actinoids.

As required by Leigh (2009), this table is clear, simple and brief.

Suggested Periodic Table Up To Z ≤ 172, Based on Dirac–Fock Calculations

A suggested periodic table up to Z ≤ 172, based on Dirac-Fock calculations on atoms and ions
Pekka Pyykkö
Phys. Chem. Chem. Phys., 2011,13, 161-168

Extended Average Level (EAL) Dirac–Fock calculations on atoms and ions agree with earlier work in that a rough shell-filling order for the elements.

[This new] Periodic Table develops further that of Fricke, Greiner and Waber [Theor. Chim. Acta 1971, 21, 235] by formally assigning the elements 121–164 to (nlj) slots on the basis of the electron configurations of their ions. Simple estimates are made for likely maximum oxidation states, i, of these elements M in their MXi compounds:

Weise's Tetrahedron

Dmitry Weise shows how it is possible to go from the Janet [left-step] periodic table formulation, to a tetrahedral formulation.

Dmitry writes:

"Three-dimensional table of the periodic law can be constructed in the form of a tetrahedron having an inner order. A comparison of the tetrahedron shells and the table of elements shows, that one tetrahedron shell corresponds to 4 periods of the 2D table."

Jess Tauber adds:

"The spheres here also aren't labeled, but I explain how they get labeled in the text accompanying the pic.  Each such period (except for s-only, which are obviously simpler) we have a 'switchback' configuration. Like a road going up a mountain back and forth to minimize verticality, or a parachute folded into a pack. There are 8 different ways to do this (4 basic types in 2 chirally opposite mappings). And the original Weise-style non-continuous tetrahedron is just another way to organize half tetrahedra."

Tresvyatskii's Periodic Table

Powder Metallurgy and Metal Ceramics, Vol. 49, Nos. 9-10, 2011:

The paper published below represents Tresvyatskii's fundamental study. It establishes the interrelation between the ionization potential and place of an element in the periodic table. Oxides with a certain composition may form only when an element is ionized to the needed degree. Hence, the ionization potential of elements is an important parameter that governs the formation of an oxide. In this regard, the dependence of the ionization potential on the place of an element in the periodic table is of paramount importance. The role of the ionization potential in the hightemperature chemistry of oxide compounds, which underlies modern oxide materials science, is especially significant. The paper is published in Tresvyatskii's original version.

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.

Alexander Arrangement of Elements, 3D Illustrated

The design of the 2012 Alexander Arrangement of Elements (AAE) follows the principles of a three-dimensional model developed by Roy Alexander in 1965: a printed representation of element information based on strict adherence to the Periodic Law, with every element data box physically and visually contiguous and continuous within the sequence of atomic numbers in generally accepted element property related columns - "...the periodic table the way it's supposed to be".

This is made possible by wrapping, folding, and joining the printed material and employing the patented p-block downslant of the element data boxes to allow the end element of a period to be adjacent to the first element of the next period.

Several unique features separate it from the previous four versions of the AAE

Designed by Roy Alexander, a science museum exhibit and teaching aid designer, the Adobe Illustrator art for the model was started by Ann Grafelman, and continued by Roy from mid 2011 through November of 2012.

Photos were provided by Theodore Gray, and Element Collection funded the printing and die cutting performed by Strine Printing in York, Pennsylvania. The model kit was first offered at Theo's PeriodicTable.com, then at Roy's AllPeriodicTables.com and the new 3dPeriodicTable.com, which site is dedicated to the 3D Forever Periodic Table only, with add-ons, application suggestions, and descriptions and commentary of all sorts.

Assembly instructions and step photos, as well as a number or completed model color photographs are included with the kit. These were developed with prototype models, and while functional, have been upgraded and accompanied by an assembly video at AlexanderArrangementOfElements.com/3D

Addendum:

Text relating to the abbreviation of the ever increasing number of elements is explained at two places on the 3D AAE illustrated periodic table model kit. One will remain with the model and one is removed at the time of assembly.

That which remains runs under the Actinoids and the d-block elements, where the lab created elements might ordinarily be expected to be found, says:

The lab created elements ordinarily found in this part of a periodic table are not to be found in nature, there can be no photographs of them, so nothing needs to be added to this element photo periodic table - ever - so it will never be obsolete, a Forever Periodic Table.

That which is removed says:

Naturally-occurring elements have been numbered variously, generally between 80 and 96, all for cogent scientific reasons.

For easier teaching and learning, we have included on this periodic table only the 92 elements actually currently existing on Earth and in the remainder of the Universe, and adding Technetium and Promethium, which, although they may have no stable forms, serve to fill what would otherwise be gaps in the sequence.

Not added for practical and educational reasons are 'elements' consisting only of pages and pages of computer data from smashing atoms in particle accelerators. Another reason is that there can be no photographs of them to show, and as a result, your arrangement is complete and never be obsolete - your Forever Periodic Table.

Included with the art of the periodic table on the die cut substrate that makes up the model is some background information about the the history of three dimensional periodic tables.

The first of these is about the discoverer of the concept of arranging the elements in periods suggested by the properties of the elements, de Chancourtois.

The second 3D periodic table information piece (on the rear of the de Chancourtois removable card) are sketches of a number of the 3D periodic tables found on the Chemogenesis website.

Wheelshaped Table of Elements

From Facebook, a Wheelshaped table of elements.

Please note the symmetry of this representation.

As a result, it is possible that element 118 is the very last one in the periodic table. We have the sequence:

2 x 14 (blue)
4 x 10 (brown)
6 x 6 (violet)
8 x 2 (green)

and, logically, neither first nor last factor can be 0 or -2 (they differ in two columns above respectively by 2 and 4). On the other hand, the coherence of the structure requires the existence of two additional elements at the beginning!

Ato Circular Periodic Table by Ramanpreet Singh Jandu

Ramanpreet Singh Jandu writes:

"The present invention relates to a device for the understanding of the periodic table and the structure of the atom together in a better way.

The device consists of seven concentric circular disks rotatable about their centre, wherein the size of the disks increases from the centre to the end like that in the structure of the atom.

Each disk is marked so as to form the sub-blocks and each disk in itself represents the periods of the periodic table.

The disks are divided into sub-blocks and labeled with elements at back side as well.

Thus the Ato Circular Periodic Table, as the name suggests, is the combination of atomic structure of the atom and that of the periodic classification of the elements."

[A] poster is designed to geek out the chemist and the mystic alike. It is a variation on the periodic table of chemical elements that have been rearranged into a circular structure based upon their proton count and chemical family, augmented with the concept of the 7 mystic elements of earth, air, fire, water, metal, wood and void. It was very interesting to work upon once I hit the correct organization of elements that they lined up almost perfectly.

Electronegativity Chart (Leach)

From Mark R Leach's paper, Concerning electronegativity as a basic elemental property and why the periodic table is usually represented in its medium form, Journal & PDF.

Due to the importance of Pauling's electronegativity scale, as published in The Nature of The Chemical Bond (1960), where electronegativity ranges from Cs 0.7 to F 4.0, all the other electronegativity scales are routinely normalised with respect to Pauling's range.

When the Pauling, Revised Pauling, Mulliken, Sanderson and Allred-Rochow electronegativity scales are plotted together against atomic number, Z, the similarity of the data can be observed. The solid line shows the averaged data:

MCAS Electron Orbital Filling

From Joel M Williams:

"While the periodic table arrangement is usefully interpreted in columns of similar behavior, it is erroneous to imply that the underlying orbitals are all the same for all the elements in the columns of a block. Sub-orbital information has been excluded! From the standpoint of chemistry, the rule of eight would have provided better imagery on which to build an orbital system than was Bohr's orb turned-sphere. A sphere is useless from a chemical standpoint. Hybridization should not have to occur to explain the simplest of molecules. Simplicity would have the electrons occupying orbital spaces that are similar in shape. Only three orbital types are actually needed to describe the electron packing of the elements. Octahedral, square-planar, and pyramidal coordination complexes of the transition elements follow logically without the need to hybridize. This brief paper describes a rational packing of electrons around a nucleus that ends up mimicking the familiar periodic table when compressed to similar behavior."

 

Modeling the MCAS Way describes this concept of "building blocks" and can be found here.

"A periodic table is constructed from the consideration of periodic properties and the application of the principal components analysis technique. This procedure is useful for objects classification and data reduction and has been used in the field of chemistry for many applications, such as lanthanides, molecules, or conformers classification. From the information given, the whole procedure can be reproduced by any interested reader having a basic background in statistics and with the help of the supplementary material provided. Intermediate calculations are instructive because they quantify several concepts the students know only at a qualitative level.

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.

Model Wooden Periodic Table

From here, and translated from Spanish:

Among the events commemorating the 75th anniversary of the creation of the School of Treball, the author of this site, B. Navarro, along with J. Semis and J. Gràcia have built a model wooden periodic table.

The table has been divided into 5 areas: representative elements, noble gases, transition elements, rare earths and finally the groups I and II of alkali and alkaline earth together. Each of these areas of the table is made with a different type of wood. The block transition elements is made with oak, ash noble gases, representative elements in cherry, sapele the rare earth and alkali/alcalinoterros beechwood.

The central idea of the model is that each element is represented by a cube of 3 cm edge so that you can see on all sides, from left to right or right to left without losing the order of increasing atomic number or the relative position of the elements:

Abstract:

The Periodic Table with a new double numerical structure, presented here is attempt to find table form which will in some new way represent the periodicity and symmetry of the Elements, with the Periodic System as base. Also this tetrahedral laminar table structure maybe will became a base for developing a new shell structure of atomic nucleus. This new rearrangement of the chemical element is based on mathematical formula which result is simple, length of the periods:

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."

"There is a periodic table, at least in terms of atomic number and electronic configuration, for every positive integer, c >= 2, with a capacity of 20c2 – 21c + 1 elements, where c is the construction index, and c equals one plus the maximum number of electrons per orbital of an atom. The c-construction index and the c-construction-index formulae are unique to this report. The maximum number of potential orbitals per sub-shell of an atom = 3n-1 where n is the index of the s, p, d, and f sub-shells":

ADOMAH Periodic Table Glass Cube

Valery Tsimmerman, of the ADOMAH Periodic Table and the ADOMAH Tetrahedron, has now used these ideas to produce a beautiful glass cube:

 

This amazing object is available for sale from Grand Illusions:

 

A Note by Philip Stewart stewart.phi@gmail.com

The cube represents 120 chemical elements etched into a cube of Optical Crystal glass. The s, p, d, and f blocks of the Janet periodic table form four rectangles, which are slices of a regular tetrahedron, parallel with two of its edges and with two faces of the circumscribed cube. All four quantum numbers are made visible in this arrangement. You can see a 2-D version on the Perfect Periodic Table website, click on the "skyscraper" version on the right to see the tetrahedron, and go to Regular Tetrahedron at foot of page for details.

The regular tetrahedron is the only form in which slices are rectangles of different shape and identical perimeter. When each orbital is represented by a square of unit edge, the rectangles representing the blocks all have the same perimeter, which is twice the length of the edges of the tetrahedron (which are of course √2 times the edges of the cube): 18 units = 2(values of n + values of ml).

Valery Tsimmerman, orahct@gmail.com, creator of the design, has written to me as follows:

"I just had some thoughts about the Perimeter Rule that is at the basis of the tetrahedral arrangement. Dimensions of the blocks are dictated by number of values of ml and number of values of n. We know that n governs quantization of energy. Recently I learned that quantization of the possible orientations of L with respect to an external magnetic field is often referred to as space quantization. (Serway, Jewett: Physics for Scientists and Engineers. 6th edition. p.1369).

"That is, ml stands for space quantization. Therefore, the Perimeter Rule reflects a direct relationship between energy and space. I think that this could have some significance. The beautiful thing about the Universe is that each type of symmetry is related to some conservation law. Symmetry in time is related to energy. Therefore, n is related to time also, so, in the Perimeter Rule we have relationship between time and space on quantum numerical level. The interesting thing is that ml can be positive and negative, while n can only be positive. Similarly, things can move in space in positive and negative directions, but time has only one direction. There is no negative time, just as there are no negative values of quantum number n."

Adomah is a variant of Adamah, Hebrew for 'dust of the earth', from which Adam was made (Genesis 2:7).

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.

Chandra's Polar Plot Periodic Table

MONOGRAPH ON ATOMS, BY Dr. N. Naveen Chandra, 543 Bellamy Road North Scarborough, On, M1H1G5, 416 439 6630, chandraalex@hotmail.com >© N.Naveen Chandra, 2014.

Abstract

A new way of graphical representation of atoms is developed and presented here. Atoms are recognized as functions of two variables A(r,Θ), where r =2,10,18,36,54,86,118 (given arbitrarily r=1,2,3,4,5,6,7) represents period and Θ representing group, is actually the angle between the groups. A mathematical solution is obtained for Θ having three distinct values of (π /9) radians, (π/18) radians and (π/27) radians which define three super groups satisfying the equation 15(π/27) +10(π/18) +8 (π /9) =2π. 15 groups of two Atoms with a transition zone of (π/27) radians is nominally called Grey Super Group (GSG). 10 groups of which 9 have four Atoms and 1 has two Atoms, also including a transition zone of (π/18) radians, is nominally called Blue Super Group (BSG). 8 groups of which 7 have 6 Atoms and one has 7 Atoms, including a transition zone of (π/9) radians is called Yellow Super Group (YSG). The group with 7 atoms is the so called reference group of Atoms 2, 10, 18,36,54,86 and 118. The GSG has 30 Atoms, the BSG has 38 Atoms and the YSG has 49 Atoms. The Atom 1 is at the centre of the Hub and does not belong to any group or period and has coordinates of (0, 0). Atom 1 having no neutrons is unique.

Janet Rajeuni

By Philip Stewart:

Janet Rejuvenated, with acknowledgement to Mazurs and to Valery Tsimmerman for the idea of using one square per orbital and of shifting the blocks so that each row represents one value of n, the principal quantum number.

The main objection people make to Janet is that He is placed at the head of the alkaline earth metals although it behaves as a noble gas. The essential answer is that electronic structure explains behaviour and not vice versa; like Ne (and unlike Ar, Kr, Xe and Rn), He has a complete shell. Similarly H, like C, is half way between a full and an empty shell, unlike the alkali metals and the halogens. I suggest a new argument: nobody finds it strange that the p block has a row of non-metals at its head (and that half its members are non-metals), so why not the s block?

Belikov's Modular Periodic Table of Chemical Elements

"I call this version of the Modular Periodic Table of Chemical Elements. I got the idea for it some time between 2005 and 2007, during the chemistry course at my university, in attempt to rationalize the clumsy common version I was being taught. I showed it to my chemistry teacher, but he didn't seem to be impressed much, so it went into the drawer. Recently I decided to resurrect it and publish somewhere. So I had a look on the web and found your excellent database, with hundreds of versions. After the first shock, I realized that only few are actually similar to my version. These are well known Janet's table and ADOMAH table. So, it appeared to me that the idea to group elements strictly according to filling of their atomic shells is not new. However, the way I have done it is slightly different from the mentioned tables. For example, s,p,d and f blocks of elements are completely autonomous and can be placed wherever desired (hence the name 'Modular'). This reflects the notion that there is little in common in chemical behavior between the elements in different blocks. Also, outer subshell type, energy level and electron count are clearly labeled, so that these parameters can be quickly determined for each element.

"Overall, I think that this version of periodic table allows easier understanding and transition from IUPAC table and could be implemented in school and university textbooks."

Jodogne's Janet New Colour Periodic Table

"This Periodic Table(click here for larger version) incorporates the Real Aufbau of Professor Pyykkö based on relativistic Quantum Mechanics, with Z continuity horizontally and vertically, by means of taking into account the ground level - energy increase upward - of the last incoming electron (the lower side of the element case is the level guide mark). A large yellow line indicates period. A gradual color for H induces a manifold chemical behavior."

Aco Muradjan's New Notation Scheme

Aco writes:

On 08.11.2014 I added an article to the General Science Journal:

"Necessity of urgent revising and changing the present IUPAC notation scheme in the Periodic Table"

The current and present modern notation scheme for the groups in the Periodic Table exist from 1985, proposed from the IUPAC Commission on the Nomenclature of Inorganic Chemistry, as recommendation. This proposal was also verified in 2005.

Because the IUPAC Commission encourages further discussions, improvements and proposals on this subject I made this new article which article investigates the possibilities for the new notation scheme in the Periodic Table. Links:

Arrangement of Elements 7th Order & Element Sequences

An exploration of some mathematics underlying the periodic table, read the PDF here, by Olivier Joseph.

Oliver says:

"May I propose you the following pattern, as the result of a personal study concerning the arrangement of the Elements, including sequences. Based on some hypothesis and as depicted in the enclosed illustrations, the elements are positioned according to a spiral function of atomic number and atomic mass, representation in 2D in a spiral form pattern, or in 3D conical helix model.

"The elements are numbered and placed consecutively along this spiral according to a specific angle, appropriately established between each element, forming a seven arm spiral pattern. With such an angle, specifically defined, a link is established between the various elements of a same group (corresponding to chemical elements with similar properties) and different layers. These latter becoming distributed among each arm of the spiral in a notable arranged way."

Schaeffer's IUPAC Periodic Table Quantum Mechanics Consistent

IUPAC Periodic Table Quantum Mechanics Consistent, Bernard Schaeffer, Journal of Modern Physics, Vol. 5, No. 3, February 24, 2014
DOI: 10.4236/jmp.2014.53020

Abstract: Most periodic tables of the chemical elements are between 96% and 100% in accord with quantum mechanics. Three elements only do not fit correctly into the official tables, in disagreement with the spherical harmonics and the Pauli exclusion principle. Helium, belonging to the s-block, should be placed beside hydrogen in the s-block instead of the p-block. Lutetium and lawrencium belonging to the d-block of the transition metals should not be in the f-block of the lanthanides or the actinoids. With these slight modifications, the IUPAC table becomes quantum mechanics consistent.

UVS Periodic Table Model of a Klein Bottle Topology

This configuration can topologically suggest the g-block cycle in the 8th period for extended periodic table.

In the Klein bottle topology as illustrated, it is plausible that after the s-block cycle in the 8th periodical cycle, the topological path continues to spiral around the outer f-block cycle to harmonically form 14 elements.

And then subjected to the spiral Möbius strip topological twist, it could resonate to form 4 more elements in the anti-cyclonic path around 17th, 18th, 1st, and 2nd angular phases of the anti-cyclonic core; this would render the 18 elemental positions for the hypothetical g-block cycle in the entire half-integral anti-cyclonic cycle of the Klein bottle topology.

Hypothetically, the topological path then moves into the cyclonic cycle, and harmonically forms its d-block and p-block cycles with 16 elemental positions to complete the 8th periodical cycle with a total of 36 elements.
