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)).
