In the covalent bond formation of carbon dioxide, carbon and oxygen atom share four pair of electrons. The carbon atom joined by four covalent bonds to two oxygen atoms. Therefore, these atoms are rearranged to form the bonds by the sharing of many valence electrons between the atoms.
Answer:
The four valence electrons of the atom of carbon are arranged to form two bonds, one with each atom of oxygen, consisted of two valence electrons each bond. Two of the six valence electrons of each atom of oxygen are arranged to form a bond with two valence electrons of the atom of carbon. That is, each carbon-oxygen bond consist of two valence electrons of the atom of carbon and two valence electrons of the atom of oxygen.
