Blue toruses = 16 protons
Red toruses = 7 nuclear electrons
Atomic number of F (9) = protons (16) - nuclear electrons (7)
Fluorine 16 nucleus decays by proton emission (left side) of
Fluorine 16
decay form
to Oxygen 15.
Oxygen 15 transformed by positron emission from a source of a photon by decomposition,
while electron component of the photon captured to the center of 
Oxygen 15,
producing Nitrogen 15
(stable).
