Why is carbon dioxide a covalent bond?

Explanation:

One atom of carbon (2.4) combines with two atoms of oxygen (2.6) to form the compound carbon dioxide CO2 (only the outer shell of carbon's electrons are shown). ... The carbon dioxide molecule is held together by the strong C=O. carbon–oxygen double covalent bonds by sharing electrons.

Note that carbon dioxide has two covalent bonds between each oxygen atom and the carbon atom, which is shown here as two lines and referred to as a double bond. When molecules are symmetrical, however, the atoms pull equally on the electrons and the charge distribution is uniform. Symmetrical molecules are nonpolar.
