Periodic Tables from the year 2017:
Alternative Periodic Table
From Useful Charts:
You'll notice that this periodic table looks quite a bit different from the one you're used to. The traditional periodic table is designed to emphasize the concept of valence, which is important for knowing which elements can easily combine with others to form compounds. In contrast, the periodic table below is designed to simply emphasize the way in which atoms are "built" (specifically, how electrons group together into shells and subshells).
It's based on a design proposed by Edward Mazurs in the 1960s. Like the traditional table, this alternative version can be used to find an elements name, number, atomic weight, state of matter, period, group, and block. However, it also contains detailed information on electron configurations and the different types of electron subshells.
New Rendering of 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."

Stowe's A Physicist's Periodic Table UPDATED
Stowe's 'A Physicist's Periodic Table' was published in 1989, and is a famous & well respected formulation of the periodic table.
Since 1989 quite a number of elements have been discovered and Jeries A. Rihani has produced an updated and extended version. Click here to see the full size .pdf version:
Clock Prism Periodic Table, Braille Version
From the prolific Nagayasu Nawa, a Braille version of the Clock Prism periodic table:
P J Stewart, a good friend of the periodic table database, has mapped a PT onto a sphere.
PJS writes: "It is Janet Rajeuni 2014 wrapped round a sphere, going back to Mazurs 1965, and Tsimmerman 2006. Arabic numerals indicate shells (values of principal quantum number); Roman numerals indicate periods."
Moran's Periodic Spiral (Updated)
Jeff Moran has updated his 1999 Periodic Spiral.
Click here for a larger version.
Jeff says: I offer the attached spiral formulation as a way of expressing the relationships of the f and d blocs to group 3:
- La and Ac are assigned to the Ln and An series, respectively
- The f block series is within, though apart from, the d block
- The group 3-ish relationship of Ln and An to Sc (and, by extension, to Y) is implied
- The group 3 status of Lu and Lr is explicit

Kurushkin's Spiral Periodic Table
Mikhail Kurushkin has a way of constructing the standard long form periodic table from the Janet Left-Step formulation.
Mikhail writes in his J.Chem.Educ paper DOI: 10.1021/acs.jchemed.7b00242; J. Chem. Educ. 2017, 94, 976?979
"Addition of another s-block to the left of the left-step periodic table [enables it] to be rolled into a spiral so that the left and right s-blocks are merged together and the number of elements is exactly 118. The resulting periodic table is called the "spiral" periodic table, which is the fundamental representation of periodicity":
University of Murcia's Oversize Periodic Table
The faculty at the University of Murcia in Spain has a giant periodic table of the elements emblazoned on the facade of the school's chemistry building.
Covering 150 m2, the table displays 118 elements identified by their symbol, atomic number, and atomic mass. "It could be the world's largest permanent periodic table placed on a wall", Pedro Lozano Rodriguez, dean of the department of chemistry at the school, tells Newscripts.
A number of local companies chipped in to place the oversize chart on the side of the building, including the energy firm Repsol, the brewer Estrella de Levante, and personal care products maker Tahe Productos Cosméticos. Lozano says the display will serve as part of an introductory chemistry lesson for incoming freshmen.
Gray's Wooden Periodic Table Table Video
Theo Gray collects elements and has put together this awesome Periodic Table Table. This week Reactions explores the science and chemistry going on inside this periodic table.
Step into his office at Wolfram Research, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and thousands of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table". Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones.
Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories.
Restrepo's Similarity Landscape
Building Classes of Similar Chemical Elements from Binary Compounds and Their Stoichiometries by Guillermo Restrepo, Chapter 5 from: Elements Old and New: Discoveries, Developments, Challenges, and Environmental Implications p 95-110.
From the abstract:
Similarity is one of the key concepts of the periodic table, which was historically addressed by assessing the resemblance of chemical elements through that of their compounds. A contemporary approach to the similarity among elements is through quantum chemistry, based on the resemblance of the electronic properties of the atoms involved. In spite of having two approaches, the historical one has been almost abandoned and the quantum chemical oversimplified to free atoms, which are of little interest for chemistry. Here we show that a mathematical and computational historical approach yields well-known chemical similarities of chemical elements when studied through binary compounds and their stoichiometries; these similarities are also in agreement with quantum chemistry results for bound atoms. The results come from the analysis of 4,700 binary compounds of 94 chemical elements through the definition of neighbourhoods for every element that were contrasted producing similarity classes. The method detected classes of elements with different patterns on the periodic table, e.g. vertical similarities as in the alkali metals, horizontal ones as in the 4th-row platinum metals and mixed similarities as in the actinoids with some transition metals. We anticipate the methodology here presented to be a starting point for more temporal and even more detailed studies of the periodic table.
