Web21 nov. 2024 · Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure. The chemical symbol for Beryllium is … Beryllium (4Be) has 11 known isotopes and 3 known isomers, but only one of these isotopes ( Be ) is stable and a primordial nuclide. As such, beryllium is considered a monoisotopic element. It is also a mononuclidic element, because its other isotopes have such short half-lives that none are primordial and their abundance is very low (standard atomic weight is 9.0121831(5)).
