Description

Chart depicting the electronegativity differences of atoms, including definitions and examples of ionic and covalent bonding in the context of electronegativity.

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
