follow the given instructions and answer the following

What I Have Learned Activity 3: Reasoning Challenge Directions: Answer the following questions in 2-3 sentences only. 1. VSEPR theory specifies "valence shelI" electrons. Explain why these are the most critical electrons for determining molecular shape? 2. Avogadro does not "waste" his time drawing a Lewis structure before determining the shape of PF3. He thinks that the shape of PF3 must be trigonal planar because there are three fluorine atoms bonded to the central phosphorus atom. a. Draw the Lewis structure for PF3. b. Was Avogadro's answer for the shape of a PF3 molecule correct? Explain c. Why is it important to draw the Lewis structure for a molecule before identifying the shape of the molecule? 3. Draw the Lewis structure of ozone, O3. Describe why ozone has a bent shape instead of a linear shape.
