Chapter 7 Student competencies
Upon completion of this chapter, students should be able to:
-
Explain what happens to the size of a given electron orbital as the number
of protons in the nucleus increases.
-
Predict the relative sizes of different atoms and ions. Explain why
these trends occur in terms of effective nuclear charge and electron configuration.
-
Understand the factors which affect the magnitude of electrostatic (Coulombic)
interactions. Apply these principles to explain periodic trends.
-
Define ionization energy and explain the periodic trends that are observed.
Use electron configuration to explain the deviations in these trends that
occur across a given row.
-
Define electron affinities and predict and explain the periodic trends
that occur.
-
Understand the reactions of:
-
Metal oxides with water
-
Nonmetal oxides with water
-
Metal oxides with acids
-
Metals with nonmetals
-
Nonmetal oxides with bases
-
Alkali and alkaline earth metals with water
