Blue toruses = 8 protons
Red toruses = 6 nuclear electrons
Atomic number of He8 = protons (8) - nuclear electrons (6) = (2)
Helium 8 decays by electron emission (from the left position) of
Helium 8 
destabilized, 
decay form
to Lithium 8
.
Lithium 8 decays by electron emission of
Lithium 8 destabilized form
through Be8
producing two He4
nucleus (stable).
