Elements & Atoms: Case Studies in the Development of Chemistry
Carmen Giunta of Le Moyne College Department of Chemistry has collected many of the original papers plus commentary dealing with eighteenth and nineteenth century science in a web book called Elements and Atoms: Case Studies in the Development of Chemistry. This web resource is highly recommended:
Concept of Chemical Periodicity
Concept of Chemical Periodicity: from Mendeleev Table to Molecular Hyper-Periodicity Patterns E. V. Babaev and Ray Hefferlin
The paper "The Concepts of Periodicity and Hyper-Periodicity: from Atoms to Molecules" was published as a the book: Concepts in Chemistry: a Contemporary Challenge. (Ed. D.Rouvray). Research Studies Press, London, 1996, pp. 24-81.
The website, here, is the original text of this paper (copyright by the authors).
The text deals with periodicity in isotopes, atoms and materials.
Seaborg's Evolution of the Modern Periodic Table
By Glenn T. Seaborg, from J. Chem. SOC., Dalton Trans., 1996, Pages 3899-3907:
"In this review, the evolution of the Modern Periodic Table is traced beginning with the original version of Dimitri Mendeleev in 1869.Emphasis is placed on the upper end with a description of the revision to accommodate the actinide series of elements at the time of World War II and the more recent research on the observed and predicted chemical properties of the transactinide elements (beyond atomic number 103).A Modern Periodic Table includes undiscovered elements up to atomic number 118 and a Futuristic Periodic Table with additional undiscovered elements up to atomic number 168 is included."

Braille Guidebook Interactive Periodic Table Study Set
Azer's Interactive Periodic Table Study Set is designed to make learning about the Periodic Table of the Elements accessible to students with visual impairments or blindness.
The tangible materials included with this study set complement APH's Periodic Table of the Elements Reference Chart and allow students to enhance their understanding of concepts consistent with the National Science Standards.
Inspired by Samir Azer, a science teacher at the Kentucky School for the Blind, this set can assist in the instruction and demonstration of concepts related to the arrangement of the periodic table, atomic structure, ionic and covalent bonding, and balancing of chemical equations to students who benefit from a hands-on, interactive model.
Special attention was given to make the materials tactually discriminable and visually appealing to the target population, yet appropriate for all students regardless of visual acuity:

The Elements by Theo Gray
As Theo (modestly... ) says:
"Much anticipated (by me at least), this is the definitive be-all, end-all book of the elements. Like my poster, it contains beautiful photographs of all the chemical elements, shining out from a deep black background. But unlike my poster, it's not limited to just one picture per element. Instead each element gets a whole 2-page spread. At 10" x 20" (25cm x 50cm), each spread is as large as the whole place mat version of my poster! And several of the more popular elements even get two spreads. There are literally hundreds and hundreds of photos in this book, nearly all of them taken by myself and my co-author Nick Mann of objects in my collection."

Periodic Table Videos: Before & After Mendeleev
Two videos by the Chemical Heritage Foundation: Part 1 Before Mendeleev and Part 2 Mendeleeve & Beyond.
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. Part 1 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. 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. Part 1 is 17 minutes long and Part 2 is just under 20 minutes.
"The Periodic Table is one of our crowning scientific achievements, but it’s also a treasure trove of passion, adventure, betrayal, and obsession. The fascinating tales in The Disappearing Spoon follow carbon, neon, silicon, gold, and every single element on the table as they play out their parts in human history, finance, mythology, conflict, the arts, medicine, and the lives of the (frequently) mad scientists who discovered them: Why did a little lithium help cure poet Robert Lowell of his madness? And how did Gallium (Ga, 31) become the go-to element for laboratory pranksters?"
"The Disappearing Spoon has the answers, fusing science with the classic lore of invention, investigation, discovery, and alchemy, from the Big Bang through the end of time."

Wonderful Life with the Elements
In this super periodic table, every element is a unique character whose properties are represented visually: heavy elements are fat, man-made elements are robots, and noble gases sport impressive afros. Every detail is significant, from the length of an element's beard to the clothes on its back. You'll also learn about each element's discovery, its common uses, and other vital stats like whether it floats—or explodes—in water.

Electronegativity Chart (Leach)
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:

"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. The final scores representation reveals an unexpected periodic table presenting some interesting features and points for discussion."
There are more than 600 periodic tables hosted by the Chemogenesis Webbook Periodic Table database, so it can be a little difficult to find the exceptional ones.
Here we present – in our humble opinion – The ten most significant periodic tables in the database.
We present the best:
The first three of our top 10 periodic tables are classic element data repositories.
They all work in the same way: click on the element symbol to get data/information about the selected element. The three are Mark Winter's WebElements, Theo Gray's Photographic Periodic Table & Michael Dayah's Ptable.
The next five examples deal with history and development Periodic Table. The first is Dalton's 1808 list of elements, next is Mendeleev's 1869 Tabelle I, then Werner's remarkably modern looking 1905 formulation. This is followed by Janet's Left Step formulation and then a discussion of how and why the commonly used medium form PT formulation, is constructed.
The internet database contains many, many alternative formulations, and these are often spiral and/or three dimensional. These exemplified by the 1965 Alexander DeskTopper Arrangement. To see the variety of formulations available, check out the Spiral & Helical and 3-Dimensional formulations in the database:
The periodic table as a motif is a useful and commonly used infographic template for arranging many types of object with, from 50 to 150 members.
There are numerous examples in the Non-Chemistry section where dozens of completely random representations can be found:
Rogue Elements: What's Wrong with the Periodic Table
An article in New Scientist by Celeste Biever (news editor at Nature), Image by Martin Reznik
Weights gone awry, elements changing position, the ructions of relativity – chemistry's iconic chart is far from stable, and no one knows where it will end
IF IMITATION is the sincerest form of flattery, the periodic table has many true admirers. Typefaces, types of meat and even the Muppets have been ordered in its image. For chemists, knowing an element's position in the periodic table, and the company it keeps, is still the most reliable indicator of its properties – and a precious guide in the search for new substances. "It rivals Darwin's Origin of Species in terms of the impact of bringing order out of chaos," says Peter Edwards of the University of Oxford.
The origins of the periodic table lie in the 19th century, when chemists noticed that patterns began to emerge among the known chemical elements when they... click here to continue:

Oliver Sacks' Table of Elements
From Radiolab (a podcast):
"As a young boy, neurologist, author and Radiolab favorite Oliver Sacks pored over the pages of the Handbook of Physics and Chemistry, fantasizing about the day that he, like the shy gas Xenon, would find a companion with whom to connect and share. That companion turned out to be the Periodic Table of the Elements itself, a relationship he's never outgrown. He introduces us to the elements that he's known and loved."
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:
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.

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.
Timelines, of The Periodic Table
By Steven Murov, a chronology of the events that have resulted in our present periodic table of the elements and a celebration of the 150th anniversary of the Mendeleev (birthday, 02/08/1834) periodic table (1869).
Race to Invent the Periodic Table
From PBS Digital Studios, a short-but-fast-moving video about the development of the periodic table during the 19th century, and a discussion about gallium:
Alphabet of Chemistry
A BBC World Service radio program, first broadcast Tue 23 Jan 2018.
The Russian chemist Dmitri Mendeleev attempted nothing less than to pull apart the fabric of reality and expose the hidden patterns that lie beneath everything in existence, from shoes and ships and sealing wax to cabbages and kings. The result was something known to almost everyone who has ever been to school: the Periodic Table of the elements. But why this particular arrangement? And why is it still the foundation of chemistry?
The presenter Quentin Cooper is joined by:
Mendeleev to Oganesson: A Multidisciplinary Perspective on the Periodic Table
Since 1969, the international chemistry community has only held conferences on the topic of the Periodic Table three times, and the 2012 conference in Cusco, Peru was the first in almost a decade. The conference was highly interdisciplinary, featuring papers on geology, physics, mathematical and theoretical chemistry, the history and philosophy of chemistry, and chemical education, from the most reputable Periodic Table scholars across the world. Eric Scerri and Guillermo Restrepo have collected fifteen of the strongest papers presented at this conference, from the most notable Periodic Table scholars. The collected volume will contain pieces on chemistry, philosophy of science, applied mathematics, and science education.
Eric Scerri is a leading philosopher of science specializing in the history and philosophy of chemistry and especially the periodic table. He is the author of numerous OUP books including A Tale of Seven Scientists and a New Philosophy of Science (2016) and The Periodic Table: A Very Short Introduction (2012). Scerri has been a full-time lecturer at UCLA for the past eighteen years where he regularly teaches classes in history and philosophy of science.
Guillermo Restrepo is a chemist specializing in mathematical and philosophy of chemistry with more than sixty scientific papers and book chapters on these and related areas. Restrepo was a professor of chemistry at the Universidad de Pamplona (Colombia) between 2004 and 2017, and since 2014 has been in Germany as an Alexander von Humboldt Fellow at Leipzig University and more recently as researcher at the Max Planck Institute for Mathematics in the Sciences.
