उत्तर
Two atoms of the same element combine to form a molecule. The bond between them is known as covalent bond.
Explanation:
When two identical atoms combine, they have the exact same electronegativity, meaning neither atom can pull electrons away from the other. Instead, they share their valence electrons equally to achieve a stable noble gas configuration. This equal sharing of electron pairs between identical atoms creates a nonpolar covalent bond.
