* Covalent Bond: Oxygen atoms form a double covalent bond in an oxygen molecule. This means that they share two pairs of electrons.
* Sharing Electrons: Each oxygen atom has six electrons in its outer shell. To become stable, they need eight electrons. By sharing two pairs of electrons, both oxygen atoms achieve a stable octet configuration.
* Strong Bond: This double covalent bond is quite strong, which is why oxygen molecules are relatively stable and difficult to break apart.
In summary: The two oxygen atoms in an O2 molecule are held together by a strong double covalent bond, formed by sharing two pairs of electrons.
