Two-Amphitheater Pyramid Periodic Table

From Chemical Education Journal (CEJ), Vol. 7, No. 2

A Novel Way of Visualization of the Periodic Table of the Elements by Alaa El-Deen Ali Mohamed, Alexandria University, Egypt.

The author writes:

"New form of the periodic table of the elements is given in this paper. This form can be seen as two amphitheater pyramids facing each other. The cubes that meet are s-elements (interior) then the p-elements then d-elements and the f-elements at last (exterior). The table can be represented by X-, Y- and Z-axes, where the Z-axis gives the number of the period that the element occupies. The table can be modeled by colored cubes helping in introducing the periodic table to the pupils early in the primary education."

Thanks to René for the tip!
