Inventing The Periodic Table

      Latter day 3D periodic tables
          for teaching & learning

Several scientists and a science exhibit designer have revived the de Chancourtois 3D periodic table concept in the 20th Century.
Some have started with a ribbon of elements in atomic number sequence and wrapped it in a spiral to vertically align elements with similar properties, which establishes the ‘periodic’ nature of the table.

Others may have merely wrapped the plane of the flat table – after ramping the element rows – escalator–like – in the p–block – and let the post Emile/Dmitri element blocks loop to allow a perfect atomic number sequence.
Some may have been seeking to resolve technical questions, and others, like Mendeleev, Courtines, Gamov and myself, aiming for a better educational tool.
