If number of electrons more in antibonding orbital the molecule become unstable. Beryllium (4 Be) has 12 known isotopes, but only one of these isotopes (9 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 9.0122). Because $\ce{Li2}$ is homonuclear, the weight that imposed on each $\mathrm{2s}$ $\ce{Li}$ atomic orbital would be almost the same.
