1. Define electronegativity.

  2. Show periodic trends in electronegativity.

  3. Demonstrate how to calculate the difference in electronegativity.

  4. Introduce polar covalent bonds.

  5. Explain that the difference in electronegativity indicates if a bond is ionic, polar covalent, or nonpolar covalent.

  6. Introduce partial positive/negative charges in bonds.

This packet should help a learner seeking to understand the preferred location of electrons in a covalent bond.
