Talk:Types of periodic tables

message: I give references to some spiral-shaped periodic systems of elements
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.
Many thanks to Peter Wothers – and courtesy of the Master and Fellows of St Catharine's College, Cambridge – comes a high quality image of the original 1862 formulation. 1862 Béguyer de Chancourtois' Vis Tellurique
Hinrichs' system is based on the relationship of what he called: "pantogens, with its atoms called panatoms, which explains the numerical relations of atomic weights and gives a simple classification of the elements."
This classification system culminated in 1867 in his spiral periodic table, which better clarified the groupings of elements. Hinrichs' classification, while distinctly different from the other periodic tables of this period, "seems to capture many of the primary periodicity relationships seen in the modern periodic table... it is not cluttered by attempts to show secondary kinship relationships."

thread_title:  Spiral shapes 

message: The "curled ribbon" form in the Gallery section includes visuals of the various atomic radii, determined on a "metallic" basis - presumably because it gives the cleanest trend. Elements that are not metallic at room temperature have had ratios assigned by some other means (curve-fitting?) that reflect this trend.
...Except for the noble gases, which are shown as having similar sizes to the subsequent alkaline metal rather than - as one would expect - the preceding halogen. I can't see any way in which this would make sense. 2A02:6B6E:D0FF:0:DCF8:7A44:3E22:72F6 (talk) 07:16, 16 January 2023 (UTC)
