Blue toruses = 209 protons
Red toruses = 125 nuclear electrons
Atomic number of Po209 = protons (209) - nuclear electrons (125) = 84 with structure here 5T+31D + 6 Li7 + 12 T + 18T.
Central rod of Po209 is 5T+31D.
The six member ring consists by 6 Lithium7 nuclei.
The second ring builds up by 12 Tritium nuclei and
The outer ring builds up by 18 Tritium nuclei and
