Electronegativity Difference and Bond Character Covalent bond - a shared pair of electrons between two atoms Electronegativity - the ability of an atom to attract electrons in a covalent bond. Electronegativity Difference, E, E = E1-E2, For example, each HââO bond in H2O has: E = EO - EH E = 3.44 - 2.10 E = 1.44. As the electronegativity difference grows from 0.00 to >3.00, the sharing of electrons becomes more skewed. First one atom becomes partially negative, -, while the other becomes partially positive, +, and the bond is polarized, a polar covalent bond.
And most textbooks will tell you approximately somewhere in the 0.5 range. So if the difference in electronegativity is greater than 0.5, you can go ahead and consider it to be mostly a polar covalent bond. If the difference in electronegativity is less than 0.5, we would consider that to be a non-polar covalent bond.
