In carbon dioxide (CO2), there are two oxygen atoms for each carbon atom. Each oxygen atom forms a double bond with
carbon, so the molecule is formed by two double bonds.
Two double bonds means that the total number of electrons being shared in the molecule is
two.
four.
six.
eight.

Four

Explanation:

Carbon dioxide (CO2) has carbon as its central atom with Four valence electrons while the oxygen atoms need two electrons each to form a stable octet structure.

Thus, two double bonds are formed with carbon in the centre covalently linked to the two oxygen atoms by its four valence electrons

four

Explanation:

Because there are two oxygen atoms and there is a double  bond

this is true is that what u needed
