Goals: Chapter 6.8 Periodic Trends in the Properties of Atoms

• Use trends to compare the properties (ionization energy, size, and electronegativity) of atoms
• Explain the trends using electron configurations, nuclear charge, shielding, and distance

Goals: Chapter 6.7 Electron Arrangements in Monatomic Ions

• Determine the likely charges for main group ions
• Explain the likely charges of main group ions using electron configurations
• Describe the difference between valence and core electrons
