Wednes-Day 2
AP Chem - we continued discussing questions from the summer assignment; most of the questions were on compound naming. Compound naming is fundamentally based on the type of compound:
molecular compounds (COVALENTLY BONDED NON-METALS...and there are only 11 of them!) use a prefix system. Ionic compounds (either METAL cations with NONMETAL anions or polyatomic ions in lattices) NEVER use a prefix.
Bio - we further discussed the criteria for life vs. non-life, and then we began a lab safety activity.
