ANALYSIS OF RESULTS

1. Examine the placement of electron configurations in Figure 9A-1. What relationship exists between an element's placement within a group and its electron configuration?
   
2. Examine your graph of atomic radius plotted against increasing atomic number. Can a periodic tendency be observed (a) across each period and
   

Bdown each group? If so, describe the indicated trends.

1. Which group has members of the largest atomic radii for a given period?
   

Which group has the smallest?

1. Examine your graph of first ionization energy plotted against increasing atomic number. Can a periodic tendency be observed (a) across each period and (b) down each group? If so, describe the indicated trends.
