Unit 4: Bonding & IMFs

Study Guide for Unit 4 is located here.

After learning about the atom we look towards when two or more atoms combine to form a compound. The nature of bonding between the atoms and their subsequent shape, properties, and behaviors will be explored in this unit. To be discussed: nomenclature, bonding, Lewis structures, VSEPR & molecular geometry, bond/molecular polarity, and intermolecular forces and attractions.
