Beryllium has 4 protons and 4 electrons. As for the number of neutrons most tipically it has 5. Otger configurations, called isotopes can be found ranging from 1 to 12 neutrons. Only 5 neutrons is stable; 6 neutrons will give it a half life of a milion years and 3 53 days. All the other isotopes are highly unstable, lasting no more than a few ...
