Why H2 is a nonpolar covalent bond?

The H2 molecule consists of two hydrogen atoms bonded together by a covalent bond. A covalent bond forms when atoms share electrons to achieve a stable electron configuration. In the case of H2, each hydrogen atom has one electron, and they share these electrons to complete their respective outer electron shells, which is the most stable configuration for hydrogen.

Now, regarding the polarity of the bond, a covalent bond is considered nonpolar when the electrons are shared equally between the atoms involved. In H2, both hydrogen atoms have the same electronegativity value (which is around 2.2 according to the Pauling scale), and since they are identical, they pull on the shared electrons with equal force. As a result, the electrons are equally distributed between the two hydrogen atoms, making the H2 molecule nonpolar.
