Chemical Bonding and Molecular Geometry
A series of lessons describing the principles of ionic and covalent bonding basics and their strength.
Ionic Bonding
By the conclusion of this discourse, the pupil shall be empowered to: Elucidate the process by which cations, anions, and ionic compounds are fashioned. Foretell the electrical charge of common metallic and nonmetallic elements, and set down their respective electron configurations.
Covalent Bonding
By the conclusion of this discourse, the pupil shall be empowered to: Describe the formation of covalent bonds. Define electronegativity and assess the polarity of covalent bonds.
Lewis Symbols and Structures
By the conclusion of this discourse, the pupil shall be empowered to: Write Lewis symbols for neutral atoms and ions. Draw Lewis structures depicting the bonding in simple molecules.
Formal Charges and Resonance
By the conclusion of this discourse, the pupil shall be empowered to: Compute formal charges for atoms in any Lewis structure. Use formal charges to identify the most reasonable Lewis structure for a given molecule. Elucidate the concept of resonance and draw Lewis structures representing resonance forms for a given molecule.
Strengths of Ionic and Covalent Bonds
By the conclusion of this discourse, the pupil shall be empowered to: Describe the energetics of covalent and ionic bond formation and breakage. Use the Born-Haber cycle to compute lattice energies for ionic compounds. Use average covalent bond energies to estimate enthalpies of reaction.
Molecular Structure and Polarity
By the conclusion of this discourse, the pupil shall be empowered to: Foretell the structures of small molecules using valence shell electron pair repulsion (VSEPR) theory. Elucidate the concepts of polar covalent bonds and molecular polarity. Assess the polarity of a molecule based on its bonding and structure.
