A covalent bond in which electrons are shared equally is called a nonpolar covalent bond.

Here's why:

* Polarity: Polarity in a molecule arises from an uneven distribution of electrons.

* Equal Sharing: In a nonpolar covalent bond, the two atoms involved have similar electronegativity. Electronegativity is the ability of an atom to attract electrons in a bond. Because the atoms have similar electronegativities, they pull on the shared electrons with equal force, resulting in an even distribution.

* Example: The bond between two hydrogen atoms (H-H) in a hydrogen molecule (H₂) is a classic example of a nonpolar covalent bond.
