Electronegativity Difference

  1. 1. Difference in Electronegativity Affects the Bond Type Electronegativity differences between bonding elements is used to predict the bond type. H2 – Electronegativity difference = 2.20 – 2.20 = 0 so a Covalent bond is formed. HF – Electronegativity difference = 4.00 – 0.96 = 3.04 so an Ionic bond is formed ELECTRONEGATIVITY DIFFERENCE Ionic Bonds • Held together by electrical attraction •Strong; hard to break Covalent Bonds • Held together by shared electrons • Not as strong
