Khan Academy: "Ionic, Covalent, and Metallic Bonds" and "Covalent Networks, Metallic, and Ionic Crystals"
Watch these lectures to reinforce the concepts covered in the reading assignment. An ionic bond occurs when one atom contributes two electrons to an electron pair and another atom contributes none. Metallic bonding occurs when many electrons occupy a large region of space and their atoms are cationic sites to balance overall charge.
