Lewis structure of CO₂ (carbon dioxide)

An example figure from the Lewis Structures generator.

Lewis structure of CO2: O=C=O with two double bonds and two lone pairs on each oxygen — The Lewis structure of carbon dioxide, CO₂: a carbon atom in the middle joined to each oxygen by a double bond. Each oxygen has two lone pairs and the carbon none, for 16 valence electrons in all, and every atom has an octet.
