When comparing be2 and h2?

Be2 is a beryllium atom that has formed a stable covalent bond with two electrons, while H2 is a hydrogen molecule that consists of two hydrogen atoms bonded together. In terms of size, Be2 is larger than H2 due to the difference in atomic size between beryllium and hydrogen atoms. Additionally, Be2 is more likely to form a covalent bond compared to H2, which is typically found as a diatomic molecule.
