Learning Objectives
- Summarize periodic trends
- Recognize the role of periodic trends on chemical properties
Summary of Periodic Trends
We have learned about the different trends. Figure 7.6.1 summarizes what we learned in section 7.5.

Uses in knowing the Periodic Properties of Elements
- Predicting greater or smaller atomic size and radial distribution in neutral atoms and ions
- Measuring and comparing ionization energies
- Comparing electron affinities and electronegativities
- Predicting redox potential
- Comparing metallic character with other elements; its ability to form cations
- Predicting what reaction may or may not occur due to the trends
- Determining greater cell potential (sum of oxidation and reduction potential) between reactions
- Completing chemical reactions according to trends
