Two atoms of element A unite to form a molecule with the formula A₂. The bond between the atoms in the molecule is 3) nonpolar covalent.
Only nonmetals can combine to form molecules of the type A₂ (e.g. F₂, Cl₂, Br₂, I₂, H₂, O₂, N₂). When nonmetals combine with nonmetals, they share pairs of electrons to fulfill the octet's rule. The bond in which elements share electrons is known as covalent.
The polarity of the covalent bond depends on the difference in the electronegativities of atoms that form it. Since A₂ is formed by 2 atoms of A (same electronegativity), the difference in their electronegativities is zero and the bond is classified as nonpolar.
