Which of the following describes the bond in H2?

In the hydrogen molecule (H2), a covalent bond is formed when two hydrogen atoms share a pair of electrons. Each hydrogen atom has one electron, and by sharing these electrons, they achieve a more stable electronic configuration resembling that of the nearest noble gas, helium. This sharing of electrons is characteristic of covalent bonds, which typically occur between nonmetals.

Covalent bonds are distinguished by the overlap of atomic orbitals to allow for shared electron pairs. In the case of H2, the bond is particularly strong due to the effective sharing of the electrons, leading to a stable diatomic molecule.

The other types of bonds, such as ionic and metallic bonds, do not apply to H2. Ionic bonds typically involve the transfer of electrons from one atom to another, resulting in charged ions, while metallic bonds involve the pooling of electrons among a lattice of metal atoms. Additionally, claiming that there is no bonding would ignore the fundamental interaction that holds the hydrogen atoms together in H2.
