Blue toruses = 142 protons
Red toruses = 82 nuclear electrons
Atomic number of Nd (60) = protons (142) - nuclear electrons (82)
Central rod of Nd142 isotope (stable) analogous with Neon 22 (stable) nuclear structure.
The six member ring consists by 6 Deuterium nuclei.
The eight member ring builds up by 8 Tritium nuclei and
the outer 12 member ring consists of 12 Lithium7 nuclei.
