Blue toruses = 19 protons
Red toruses = 11 nuclear electrons
Atomic number of O (8) = protons (19) - nuclear electrons (11)
Oxygen 19 decays by electron emission (from a side position) of Oxygen 19 producing Fluorine 19 nucleus (stable)
The electron can liberated only from a side position, not as depicted in pictures, which has made for the purpose of symmetry.
