WebBeryllium-8 (8 Be, Be-8) is a radionuclide with 4 neutrons and 4 protons.It is an unbound resonance and nominally an isotope of beryllium.It decays into two alpha particles with a half-life on the order of 8.19 × 10 −17 seconds. This has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements.
