Blue toruses = 120 protons
Red toruses = 70 nuclear electrons
Atomic number of Sn120 = protons (120) - nuclear electrons (70) = 50, with structure 2T+18D + 6 Li7 + 12T.
The central nanotube of Sn120 is 2T+18D, stable.
The six member ring consists by 6 Lithium 7 (stable) nuclei.
The next 12 member ring consists of 12 Tritium nuclei.
