Blue toruses = 8 protons
Red toruses = 6 nuclear electrons
Atomic number of He (2) = protons (8) - nuclear electrons (6)
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).

Helium 8 electron emission decay mechanism through Lithium 8 isotope elemental atomic nucleus and the subsequent electron emission produce two Helium 4 nuclei (= alpha particles) as stable product of Be8 decay.
