%N A shell geometric model of the nucleus. The location of the magic numbers. A triangle.

%C The magic numbers of the atomic nucleus: 2, 8, 20, 28, 50, 82, 126. 0 is the location of a magic number. 10 or 11 is equal to 2 protons (or neutrons). 1110 or 1111 is equal to 2+2 protons (or neutrons). 111111 is equal to 2+2+2 protons (or neutrons)... The 2D model is a triangle and a spiral. The 3D model is a double tetrahedron and a double spiral.
