Chemical Elements Pyramidal Diagram

A Chemical Elements Pyramidal Diagram by Thomas Zerkov.

"The present work introduces a new arrangement of the chemical elements. Unlike the most popular existing arrangements, which are two-dimensional, this new arrangement is three-dimensional. It organizes the elements in a pyramidal structure of four levels, giving a clear spatial expression of different relations between the chemical elements. Since the three-dimensional structures are harder to perceive than the two-dimensional ones, the present work also suggests a two-dimensional table representation of the three-dimensional pyramidal diagram, where the four levels are all placed in a single plane, instead of one above the other."
