6. Which table do you think would be easier to use if you were only interested in finding atomic numbers?
7. To how many significant figures is the atomic mass of lithium given?
8. Compare the keys to periodic tables A and B to the key to the periodic table in your textbook. What other information is provided
in your textbook’s periodic table that is not provided in the examples shown above?
9. In the Appendix of your textbook, the elements are listed in alphabetical order along with some properties. Discuss some of the
advantages and disadvantages of this type of organization of data compared to the periodic table.
2. Understand how the periodic table is organized including atomic number, atomic mass, periods, groups and
families, metals, nonmetals, and metalloids.

Periods and Groups
o Periods are the horizontal rows across the table. They start with Period 1 at Hydrogen and Helium and
proceed down the table. Label each period with it’s number in Red.
o Groups are the columns going up and down the table. The start with Group 1 that includes H, Li, Na, K,
Rb, Cs, and Fr. They increase in number as you go across the table. Label each Group with it’s number
in Blue.
Families
o Are groups of elements with similar properties. Please indicate the following families on your table.

5. Use periodic trends such as atomic radii and electronegativity to identify elements with similar chemical and
physical properties.
Periodic Trends in Ionic Radii
Objective
Make a graph of ionic radius versus atomic number and use the graph to identify periodic and group trends.
MATERIALS
graph paper
PROCEDURE
Use the data presented to plot ionic radius versus atomic number.
ANALYSES AND CONCLUSIONS
1. Describe how the size changes when an atom forms a cation and when an atom forms an anion.
2. How do the ionic radii vary within a group of metals? How do they vary within a group of nonmetals?
3. Describe the shape of a portion of the graph that corresponds to one period.
4. Is the trend across a period similar or different for periods 2, 3, 4, and 5?
5. Propose explanations for the trends you have described for ionic radii within groups and across periods.
2. Relate an element’s electron configuration to the location on the periodic table.
Use an element’s location on the periodic table to determine electron configuration.
