Polyatomic Ion Quiz #1 was administered...we then introduced the ions from set #2 (the "-ite"s, di-/bi-, and hypo-/per- ions) and described ways of relating these formulas to the "baseline" -ate ions that we learned in set #1. We continued work on the POGIL activity and began defining some of the basic molecular geometries...linear, trigonal planar, tetrahedral, trigonal pyramidal and bent.
