Helium 5 nucleus, destabilized form
Nuclear structure of

Helium 5 

(half life = 700 yoctos). Move mouse on image for decay form of Helium 5 nucleus.

Blue toruses = 5 protons
Red toruses = 3 nuclear electrons

Atomic number of He5 = protons (5) - nuclear electrons (3) = (2)

Helium 5 decays by neutron emission (from the left side) of Helium 5 decay form and He 4 nucleus (alpha particle) produced.
