The carbon dioxide molecule is linear. The electronegativities of C and O are 2.5 and 3.5 respectively. Based on these values and on consideration of molecular geometry, the 
bond is and the molecule is
Electronegativity refers to the ability to attract shared electrons by an atom in a molecule. The difference in electronegativities between two atoms indicates the type of bond that forms when they combine. If the difference in electronegativities between the two atoms is lesser, neither atom can remove the shared electrons from the other, and the bond is covalent. If the difference in electronegativities is higher, the atom will completely remove the bonding electrons from the other atom (electron transfer), and the bond will be ionic. So, metals with low electronegativities bond with nonmetals with high electronegativities to form ionic compounds.
A bond can be so polar that an electron transfers from one atom to another, resulting in a true ionic bond.
¶So how can we determine the degree of polarity? Scientists devised an electronegativity scale to determine how many electrons atoms of any element attract. An electronegativity is a unitless number; the higher the number, the more electrons an atom attracts.
