Middle School Chemistry: Chapter 4 - The Periodic Table and Bonding
The Periodic Table and Bonding are the topics of the fourth chapter in the middle school chemistry unit. Class members demonstrate their understanding of how atoms form covalent bonds by drawing the bonds between given molecules. Also, they create models to explain the formation of ions and ionic bonding, learn how to draw Lewis dot diagrams representing valence electrons and ionic or covalent bonding, and examine energy-level models of the Periodic Table. The six lessons include discussion questions, activities, reference materials, and links to videos.
