Blue toruses = 19 protons
Red toruses = 11 nuclear electrons
Atomic number of O19 = protons (19) - nuclear electrons (11) = (8)
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.
