1. Review the Lewis structure, formal charges, resonance, and VSEPR model sections in your lecture textbook. 2. Draw the Lewis structure for each of the following species showing all valid resonance structures and labeling any atom with a non-zero formal charge and give the name of the predicted geometry around the central atom for each. a. \( \mathrm{AlF}_{4}{ }^{\circ} \) b. \( \mathrm{IO}_{2}{ }^{-} \)(give both valid resonance structures) c. \( \mathrm{SeO}_{3}^{2} \) d. \( \mathrm{SF}_{5} \) give three valid resonance structures) 3. List all elements that cannot have an expanded octet. Cite source.
