Blue toruses = 17 protons
Red toruses = 11 nuclear electrons
Atomic number of C (6) = protons (17) - nuclear electrons (11)
Carbon 17 decays by electron emission (from a side position, not indicated) of Carbon 17 to Nitrogen 17 (half life = 4.173 s).
Nitrogen 17 decays by electron emission (from a side position, not indicated) of Nitrogen 17 to transitional Oxygen 17 and
subsequently a neutron emission of transitional (activated) Oxygen 17 decay form producing Oxygen 16 stable nucleus.
