Blue toruses = 19 protons
Red toruses = 12 nuclear electrons
Atomic number of N19 = protons (19) - nuclear electrons (12) = (7), with structure T T D T D T T = 5T+2D
Nitrogen 19 decays by electron emission to to Oxygen 19 nucleus, which has a half life = 27 s
In reality the electron and the subsequently emitted neutron can liberates only from one of the end position of proton nanotube (not indicated).
