Module 7: Chemical Bonding and Molecular Geometry

• 7.1 Ionic Bonding
• 7.2 Covalent Bonding
• 7.3 Lewis Symbols and Structures
• 7.4 Formal Charges and Resonance
• 7.5 Strengths of Ionic and Covalent Bonds
• 7.6 Molecular Structure and Polarity

At the completion of this chapter, students should be able to:

• Define electronegativity, and be able to identify and distinguish between an ionic bond and a covalent bond, and a polar covalent bond and a nonpolar covalent bond
• Draw the Lewis dot symbols of the main group atoms, and use them to draw Lewis structures and resonance structures of small molecules and ions, including any formal charges
• State the octet rule and identify exceptions
• Arrange ionic compounds in order of increasing lattice energy
• State the molecular geometry and bond angles, the polarity, and the hybridization of any non-hydrogen atom if given a Lewis structure
