Isotopes of beryllium

Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance of two alpha particles and nominally an isotope of beryllium. This has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements.
