Answer:
Carbon shares four of its electrons, and each oxygen shares two of its electrons.
Step-by-step explanation:
O=C=O
In CO₂ carbon oxide is the central atom that is surrounded by two oxygen atoms. CO₂ has a linear structure. Each of the two oxygen atoms forms a double bond with the central C atom. C has four valance electrons and each O atom has 6 valence electrons. In the formation of a double bond each O atom shares two electrons with the central C atom.
