Dmitri Mendeleev's first published table included all the known elements and left space for the elements his periodic system predicted were still undiscovered. The periodic table on the website of the International Union of Pure and Applied Chemistry avoids making a decision about whether La and Ac or Lu and Lr are group 3 elements.
The left-step periodic table, invented by Charles Janet, is strictly based on atomic orbitals and electron-filling order. You might also like Periodic Table. Periodic Table Ceiling, Elemental Pups.

Title: The periodic table is an icon. Submit Sending Gerald Eadie January 8, PM. For proponents of the Left Step periodic table, it is not necessary to calculate g-block and the matching s-p-d-f components.
Paul Eckler January 9, PM. The periodic table is a popular symbol of chemistry. But why should we have only one? Why not allow those who specialize to design their own for their own purposes? Chuck Schroer January 9, PM. I'm just wondering if there is a more three dimensional approach that needs to be developed to better show the elemental associations.
A linear table might be too restrictive? Maybe a spherical concept or pyramidal one? Maybe an ellipsoid I think sometimes we get caught up in one way of looking at things when using another way could be more helpful. I am not an expert, I just have a feeling that those who are trying to build this puzzle are looking at it the wrong way. Eisa M March 15, AM. Recently thought the same!
Sadly think that the leading representation of data has to shift to 3D before it becomes 'the' "table". Robert Parsons January 9, PM. I wonder if it might it not be more accurate at least for now to say that most of the transuranic elements were "invented" rather than "discovered. While it is certainly possible that all these higher MW synthesized elements might exist naturally somewhere in the universe perhaps within the hearts of stars , it is unlikely that any of them exist naturally on Earth and it is also possible that none of them exist naturally anywhere.
The periodic table is best viewed as a paradigm of chemistry. The pictorial representation of this concept has varied over time and is still evolving.
One of the rarely mentioned formulators of this paradigm is John F. In case anyone doubts that he was a chemist he was the son and collaborator of William Herschel and received many awards in astronomy and geology , he was the Chair of the Chemistry Section of the British Association for the Advancement of Science. He was one of the developers of photography every pun intended and was the father of chemical spectroscopy.
Valery Tsimmerman January 9, PM. According to some physicists the end of the periodic table is near. See Phys. University of Toronto physicists Bob Holdom, Jing Ren, and Chen Zhang predict that nuclei of elements with atomic masses slightly heavier than might not be composed of familiar protons and neutrons, but would rather be up and down quark matter matter, or udQM. This would mean punctuation mark in the periodic table near or at element On a different note, I agree with Scerri's position.
Modern periodic table should not depart too far from spectroscopic and quantum mechanical data. Fifteen element f-block flies in the face of what QM teaches. Paul C. Li January 9, PM.
