Figure 1. - The Double Tetrahedron Structure of the Nucleus

Representing both protons and neutrons with equal spheres and arranging them in fcc structure the number of protons in the outer layers of a tetrahedron formation is the same as the number of possible states of the principle quantum numbers.
(a) The number of spheres in a two dimensional closed packing arrangement forming equilateral triangles.	(b) The number of spheres in two consecutive layers of the tetrahedron formation
(c) The same tetrahedron formation can be developed by adding the new layers to alternate sides.	(d) Assuming a proton-neutron ratio of one the outer layers of the tetrahedron contain the same number of protons as predicted by quantum theory.
