Carbon dioxide (CO₂) it is a molecule with liniar geometry in which the carbon atom is bonded to oxygen atoms by double bonds. Each oxygen will have two lone pairs a electrons that are not involved in the chemical bonds.

Chemical diagram with the lone pairs represented, is found in the attached picture.
