Today in class we began our unit on bonding. Each student defined bonding in their own words and then shared the definitions with each other. We compiled a list of definitions to compare and contrast. Then we watched a short music video detailing the different types of bonding. I told the story of bonding as a fairy tale based on the land of the elements. We learned how to model valence electrons, the difference between cations and anions, and how to determine an oxidation state for the main group elements. Finally, we learned how to write formulas for binary ionic compounds. (Remember to criss-cross and simplify) We ended class today by doing a quick lab on page 199. You do have homework for Thursday - a hand-out to review the concepts from class today. Also, do not forget to study your polyatomic ions.
See you all on Thursday,
Mrs. E
