Type of bond in hydrogen molecule

The type of bond present between hydrogens in a hydrogen molecule is a sigma bond.

Explanation

A sigma bond is a type of covalent bond in which the electron density is concentrated along the axis connecting the two bonding atoms. In the case of hydrogen molecule, each hydrogen atom shares its single electron with the other hydrogen atom, resulting in the formation of a covalent bond. The two electrons are shared equally between the two atoms, and the electron density is concentrated along the axis connecting the two hydrogen atoms. This bond is called a sigma bond.

Pi bond, ionic bond, and metallic bond are not present in a hydrogen molecule. A pi bond is formed by the sideways overlap of two atomic orbitals, which is not observed in hydrogen molecule. An ionic bond is formed by the transfer of electrons from one atom to another, which is not observed in hydrogen molecule as both atoms have the same electronegativity. A metallic bond is observed in metals, where the valence electrons are delocalized and can move freely throughout the metal lattice, which is not observed in hydrogen molecule.

In summary, the type of bond present between hydrogens in a hydrogen molecule is a sigma bond, which is a type of covalent bond in which the electron density is concentrated along the axis connecting the two bonding atoms.
