Final answer:
A covalent bond between two elements with identical electronegativities is a nonpolar covalent bond, which involves equal sharing of electrons resulting in a balanced charge distribution.
Step-by-step explanation:
If two elements with identical electronegativities form a covalent bond, they share the electrons equally, and the bond is nonpolar covalent. A nonpolar covalent bond forms when there is equal sharing of electrons between the two atoms, leading to a balanced distribution of electrical charge. For instance, molecular oxygen (O₂) forms a nonpolar covalent bond as the two oxygen atoms share the bonding electrons equally and have the same electronegativity.
