Define electronegativity.
Show periodic trends in electronegativity.
Demonstrate how to calculate the difference in electronegativity.
Introduce polar covalent bonds.
Explain that the difference in electronegativity indicates if a bond is ionic, polar covalent, or nonpolar covalent.
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.
