LowHigh(Pauling)
No dataThe trend
Electronegativity increases from left to right across a period and decreases down a group, so the highest values sit at the top right and the lowest at the bottom left. Fluorine is the most electronegative element. Helium, neon and argon have no Pauling value because they form no stable compounds. The difference in electronegativity between two atoms predicts the bond between them: a large difference gives an ionic bond, a small one a covalent bond.
