D plot io. Analyze and Conclude 1. Compare How does the size change when an atom forms a c cation and when an atom forms an anion? 2. Describe How do the ionic radii vary within a group of metals? How do they vary within a group of nonmetals? 3. Describe What is the shape of a portion of the graph that corre- sponds to one period? 4. Compare and Contrast Is the trend across a period similar o different for Periods 2, 3, 4, and 5? 5. Explain Propose explanations for the trends you have described for ionic radii within groups and across periods.
