A nonpolar covalent bond typically occurs between atoms of the same element, as they have identical electronegativities and share electrons equally.
Among the pairs listed:
- Ba (Barium) and O (Oxygen) would form an ionic bond since Ba is a metal and O is a nonmetal.
- C (Carbon) and O (Oxygen) have different electronegativities and would form a polar covalent bond.
- N (Nitrogen) and Cl (Chlorine) also have differing electronegativities, leading to a polar covalent bond.
- B (Boron) and Li (Lithium) both are metals but have different electronegativities and would not form a nonpolar covalent bond.
None of the pairs listed form a nonpolar covalent bond because they all involve atoms with different electronegativities. If the question allows for re-evaluation or inclusion of atoms not listed, consider pairs like N and N, or H and H, which would form nonpolar covalent bonds. However, based on your list, none meet this criterion.
