This chapter presents the periodic table as a valuable organizational tool for chemists. Using examples and diagrams, the chapter describes trends in atomic and ionic properties found within the table. You will learn to classify elements by electron configuration, and to explain trends in atomic radii, ionic radii, ionization energies, and electronegativity.

In this chapter, you will learn: to explain why you can infer an element's properties based on those of other elements in the periodic table to use electron configurations to classify elements to interpret periodic trends in atomic radii, ionic radii, ionization energies, and electronegativity
