WebEquation (4) states that a non-polar bond will result when the difference between the ionization potential and the electron affinity is the same for both atoms joined by the bond. If the quantity I X - A X is greater than I Y - A Y, then the product X-Y + will be energetically favoured over X + Y-.Thus the quantity (I - A) provides a measure of the ability of an … Webatoms increases, meaning that the bonds become more polar and the atoms carry greater charges. When the electronegativity difference is above 1.7, an electron has been transferred from one atom to the other, and the resulting ions form an ionic bond. Figure 3 Covalent bonds are polar when the electronegativity difference is > 0.4 and nonpolar …
