The bond between hydrogen atoms in a gas where electrons are shared equally is called a covalent bond.

Here's why:

* Covalent bond: A covalent bond is formed when two atoms share electrons to achieve a stable electron configuration.

* Equal sharing: In the case of diatomic hydrogen (H₂), the two hydrogen atoms each have one electron. By sharing their electrons, they both achieve a stable configuration resembling that of helium (two electrons in the outermost shell).

Since the hydrogen atoms are identical, the electrons are shared equally between them. This is a nonpolar covalent bond because there is no difference in electronegativity (tendency to attract electrons) between the two atoms.
