(stable).

Blue toruses = 9 protons
Red toruses = 5 nuclear electrons

Atomic number of Be (4) = protons (9) - nuclear electrons (5)

If you like to say, Be9 contains only one neutron (= the central proton-electron pair). The other 4 neutons are not true because the 4 nuclear electrons are common with two neighbour protons each in turn.
