Step-by-step explanation:
Two oxygen atoms bonds with each other via covalent bonding.
In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.
- Two atoms of the same kind having zero electronegativity difference forms this covalent bonds.
- There is equal sharing of electron pair between the atoms and there is no electrostatic charge on the molecule.
For the oxygen atom with 6 valence electrons;
two electrons are shared by each atoms to make a complete octet and a stable molecule.
