Pyramid (Stack) Periodic Table

The Janet Periodic Table of Elements (1928) may be re-arranged as a series of square matrices.

The matrices are of different sizes and each matrix organizes the atomic orbitals into square concentric rings. Each cell may be assigned an atomic number which also identifies a “most significant electron”. The matrices may be stacked vertically to form a periodic Pyramid Stack of Elements as shown below.

The sub-atomic particles may also be arranged as square matrices. These matrices may be stacked. Read more here.
