Béguyer de Chancourtois' Vis Tellurique
The French geologist , Alexandre-Émile Béguyer de Chancourtois was the first person to make use of atomic weights to produce a classification of periodicity. He drew the elements as a continuous spiral around a metal cylinder divided into 16 parts. The atomic weight of oxygen was taken as 16 and was used as the standard against which all the other elements were compared. Tellurium was situated at the centre, prompting vis tellurique, or telluric screw.

Some more information:
Chancourtois' original formulation includes elements in their correct places, selected compounds and some elements in more than one place. The helix was an important advance in that it introduced the concept of periodicity, but it was flawed.
It has been suggested that Chancourtois called his formulation a telluric helix because tellurium is found in the middle. However, most elements are found as there their 'earths' – tellus, telluris – or oxides, which for a mineralogist would have been highly significant.
The formulation was rediscovered in the 1889 (P. J. Hartog, "A First Foreshadowing of the Periodic Law" Nature 41, 186-8 (1889)), and since then it has appeared most often in a simplified form that emphasizes the virtues and eliminates its flaws. [Thanks to CG for this info.]

Alexander Arrangement of Elements
The Alexander Arrangement of Elements is a 3D periodic table concept based on strict adherence to the Periodic Law, and, like the first representation of elements in periods by de Chancourtois, connects every element data box in unbroken order.
Roy Alexander, a Brooklyn born science museum exhibit and teaching aid designer, has told me in a personal communication: "I came up with the idea (being ignorant of anything but the flat Sargent Welch charts) in 1965. I wasn't able to patent [the downslant in the p-block] until 1971." (U.S.Patent #3,581,409)
At the time Roy had no idea that others had employed a similar technique to build a 3D table - including the very first periodic table developer, de Chancourtois, who is often credited with being the original discoverer of the periodicity of elements and the originator of the three-dimensional method of element arrangement and representation.
These 3D forms attempt to return the Seaborg separated f-block to its proper position in the table rather than remaining exiled. This, and contemporary attitudes about Hydrogen as being in more families than one - is uniquely addressed in Roy's 3D models.
Subsequent study of the Periodic Law and the periodic table's value in education convinced Roy that the basic rationale for developing the Alexander Arrangement of Elements was only one of the many good reasons for producing it for the public to share, so he sought and was granted a U.S. patent on the p-block downslant in order to manufacture and market the AAEs as teaching/learning aids.
Roy Alexander's goal of introducing the AAE into classrooms, laboratories, chemistry textbooks, and reference material remains the same today, but rather than replacing the conventional charts, its niche in education is at the very point that a lesson on arrangement of atoms into a chart begins. Element sequencing (vs. 24 breaks/gaps) credits the chart as well as the Periodic Law, which establishes subsequent confidence in the common flat charts, much as the world globe establishes the reality, and flat printed projections - maps - are vital (and relished) for convenience.
The first commercial production of Alexander Arrangements was in 1995, when Roy pioneered by constructing a website - periodictable.com - for marketing. Three versions were printed: two versions for student entry of element symbols, the larger die-cut for easier assembly.
An even larger model was produced with basic element data printed in the boxes, also die cut. These were printed on white card stock, with black ink.
Another version (below) was produced in conjunction with ATMI's annual report in 2000. This was added to Roy's product offerings, called the DeskTopper, and is still available. They are die cut to form a 7.25" high model with the f-block position attached after La, but can be altered to put La on the f-block. (See AAE Features at the top of this page.)
Besides the hands-on educational application, the DeskTopper can be used as a pen & pencil caddy, and flattened without losing the continuity of the element data. This flattened form has suggested design of a Braille periodic table of the same format, and this is also being pursued.
Marketing the Alexander Arrangements was moved to AllPeriodicTables.com in cooperation with Theodore Gray in 2006, who purchased the PeriodicTable.com domain name and funded the production of Roy's newest model, illustrated with Theo's amazing element photos.
For the first time, the elements beyond those naturally occurring have been omitted from a modern periodic table, simplifying initiation to chemistry. This factor denies the concept of obsolescence, and this version has been called the Forever Periodic Table. Details of this new 3D periodic table model kit have been placed at 3DPeriodicTable.com.
Further AAE information and images may be found at the Alexander Arrangement website.

Mann's Spiral Periodic Table
From AT Mann:
Gary Katz says: "The Periodic RoundTable is a unique three-dimensional model of the Periodic Table, an elegant spatial arrangement of the chemical elements that is both symmetrical and mathematical. It is the ultimate refinement of Mendeleev's scheme, one that will take us into the twenty-first century and beyond. The Periodic RoundTable possesses such a high degree of order because it is based exclusively on the system of ideal electronic configuration, which in turn is the basis of periodicity among the elements. In the Periodic RoundTable the electron shells are filled in the same order as the elements themselves appear, demonstrating a holistic relationship between the chemistry of the elements and the orbital descriptions of their electrons."

On John Pratt's website there is an article that is both an introduction to Helen Pawlowski's model of the atom and to her Circular Periodic Table, as well as a book review of her book The Visualization of the Atom (Riverton, UT: Pawlowski Family Trust, 1990). First Helen and her work are introduced, then the model's strengths and weaknesses are summarized:
Circular Model of the Atom: Opposition in the Elements
The Circular Model of the Atom is a circular periodic table that shows atomic structure in addition to periodicity. Unlike any other periodic table or model, it demonstrates that the atomic structure has an inherent dipole magnet that create positve and negative fields and elemental qualities at the atomic level.
The Circular Model of the Atom was created by Helen A. Pawlowski in the 1980s, and published in her work, Visualization of the Atom.
Her brother, Paul A. Williams extended many of Helen's ideas with his examination of the standard model using Helen's Circular Atom Model. This website contains some of Helen's ideas and Paul's writings.

Hydrogen is shown at the center, atomic numbers and symbols form an unbroken spiral, and element groups 1 through 18 (noble gases, alkali metals, halogens, etc.) are displayed by colored arcs. Beginning chemistry students can visually see the continuity of atomic numbers in the Cyclical Continuum as a way to introduce and orient them to the Periodic Table. Advanced chemistry students can test their understanding of the Periodic Table's organization by applying that knowledge to interpretation of the Cyclical Continuum."

Steve Jensen's "In-Finite Form"
"I'm a figurative sculptor, living in Minneapolis MN. A few years ago, while looking at a two dimensional version of the periodic table, I too wondered if it would be possible to create a Periodic Table without any visual breaks in its numerical sequence. Although I had never seen anything other than the rectangular flat table, I thought I might be able to solve this spatial continuity problem three dimensionally. I also wanted to limit myself to using a 3-D "line" that had no sudden changes in direction. After coming up with what I thought was a new and unique sculptural resolution, I put the project aside. Only recently (after re-building my paper model out of a translucent material) did I do some research on the web, and immediately recognized the strong likeness between my version and the Alexander Arrangement. Even more surprising was my models' visual similarity to Crookes' figure eight design from some 111 years ago.
"Although there are obviously many inventive and well thought out responses to this design challenge, I believe that my solution is a unique one, and an improvement over some of the previous three dimensional forms. The "line" of my model allows for contiguous numerical placement of all the symbols (while maintaining group continuity along its vertical axis), even as the shape of its plan view makes visual reference to the well-known symbol for infinity. What's more, in my version, the Lanthanide & Actinide series do not occupy a separate field but are fully integrated into the continuous linear flow. This piece, which I've entitled "In-Finite Form" speaks to the mystery of the endless flow of space, even as it folds back onto itself within the confines of a finite system."

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.

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
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:
That which is removed says:
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.

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.

"I would like to submit you an hexagonal periodic table. It's structured in different rings. The elements are ordered on their metallic characters so in the inner rings there are noble gases and nonmetals while in the outer rings there are alkali and alkaline earth metals. I based the order on the typical metallic characteristics: low ionization energy, electron affinity, etc... "

UVS Periodic Tables
From the Universal Vortical Singularity (UVS) website, two related formunations from the nucleosynthesis in the universe section, one showing a "manifold dual-core 3-sphere hypersphere topology", and the other showing a "dual-core Möbius strip topology":
Clock Periodic Table
Prof. Martyn Poliakoff of the University of Nottingham, and star of the Periodic Videos YouTube Channel, explains how he was given a periodic table clock by a Japanese School teacher... which he likes very much:

Grainger's Elemental Periodicity with "Concentric Spheres Intersecting Orthogonal Planes" Formulation
From Tony Grainger, an Elemental Periodicity formulation with concentric spheres intersecting orthogonal planes.
There are two images of this 3D formulation: an "inside_corner_below/outside_corner_above" (top image) and an "outside_corner_below/inside_corner_above" lower image.

Scott Van Note Periodic Table Sculpture
On the Saatchi Art website, a 3D periodic table Sculpture by Scott Van Note.
Sculpture: Metal (Bronze). Ten made for the local ASM international chapter.
Loops and changes of direction show electron shell filling. S,P,D,F with S just a change of direction. Continuous spiral from top to bottom. New loops introduce as the electron shell would. Does not show the out-of-order shell filling.
Keywords: periodic, science, sculpture, functional, nerd
