Chapter 12 Chemical Bonding
Chapter 12 30 • What if the two atoms in a covalent bond have the same or similar electronegativities? • The bond is not polarized and it is a nonpolar covalent bond. If the electronegativity difference is less than 0.5, it is usually considered a nonpolar bond. • The diatomic halogen molecules have nonpolar covalent bonds.
