WebElectronegativity and Bond Type. The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic. scrapbooking cartehttp://www.chem.uiuc.edu/rogers/text7/tx71/tx71.html scrapbooking cartes anniversaires femmes tutoWebElectronegativity and Predicting Bond Types The ability of an atom to lose or gain electrons is called electronegativity.
