118 elements as electron shells

Concentric rings are electron shells (period 1 to 7, inner to outer). Angular sectors are orbital blocks in fill order — s, f, d, p — sized to their capacities of 2, 14, 10, and 6 electrons, so going clockwise around any ring follows atomic number. Hover for details, click to open Wikipedia.

Chemistry view. Nobles rotated straight up. Helium joins them at the centre by closed-shell logic. Hydrogen straddles both columns adjacent to the nobles — alkali on one side, halogen on the other — making its perennial dual citizenship visible. Period 1 is drawn as a tight inner ring so the H/He/H trio reads as a single small motif.
