Blue toruses = 18 protons
Red toruses = 9 nuclear electrons
Atomic number of F18 = protons (17) - nuclear electrons (8) = 9 with structure 9D.
Fluorine 18 transform by positron emission from a source of a photon decomposition,
while electron component of the photon captured by
Fluorine 18 and Oxygen 18 produced (stable).

The nuclear composition of the Fluor-18 isotope, nuclear structure of the F18 atom, nucleus of the Fluor-18 element. Positron emission decay of Fluorine-18 with gamma photon capture.
The structure of F18 nucleus appears balanced and symmetrical, yet it is still electron-deficient. Presumably, extremely high pressure stabilizes these longer structures in a neutron star.
