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.

Island of Stability
From Wikipedia: The island of stability in nuclear physics describes a set of as-yet undiscovered isotopes of transuranium elements which are theorized to be much more stable than others. The possibility was proposed by Glenn T. Seaborg in the late 1960s: Prospectd for Further Considerable Extension of the Periodic Table, J.Chem.Educ., 46, 626-633 (1969) and reprinted in Modern Alchemy: Selected Papers of Glenn T. Seaborg (1994).
The hypothesis is that the atomic nucleus is built up in "shells" in a manner similar to the structure of the much larger electron shells in atoms. In both cases, shells are just groups of quantum energy levels that are relatively close to each other.

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."

Chemical Elements Pyramidal Diagram
A Chemical Elements Pyramidal Diagram by Thomas Zerkov.
"The present work introduces a new arrangement of the chemical elements. Unlike the most popular existing arrangements, which are two-dimensional, this new arrangement is three-dimensional. It organizes the elements in a pyramidal structure of four levels, giving a clear spatial expression of different relations between the chemical elements. Since the three-dimensional structures are harder to perceive than the two-dimensional ones, the present work also suggests a two-dimensional table representation of the three-dimensional pyramidal diagram, where the four levels are all placed in a single plane, instead of one above the other."

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."

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.

ADOMAH Periodic Table Glass Cube
This amazing object is available for sale from Grand Illusions:
A Note by Philip Stewart firstname.lastname@example.org
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, email@example.com, creator of the design, has written to me as follows:
Adomah is a variant of Adamah, Hebrew for 'dust of the earth', from which Adam was made (Genesis 2:7).

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.

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.

Alexander Arrangement Unwrapped... and Rewrapped
In mid-2019 Roy Alexander – of the Alexander Arrangement – produced an intriguing new formulation in sketch form that shows the p, d & f blocks moving away from the s block in three dimensional space:
Roy has now expanded this into a full blown new formulation. (Click image to enlarge):
