“A Tale of 4 Electrons” due Tuesday, 3/8

After studying chapters 12.1, 13, and 14.1, you should be able to:

·  Explain why most atoms form chemical bonds.

·  Differentiate among properties of ionic, covalent, and metallic bonds.

·  Compare and contrast the properties of ionic and molecular compounds.

·  Classify bonds as ionic, covalent, or polar based on electronegativity differences.

·  Create Lewis structures for covalent compounds containing single, double, and triple bonds, including resonance structures and exceptions to the octet rule.

·  Use covalent radii to calculate bond lengths.

·  Explain the modern interpretation of resonance bonding.

·  Calculate the formal charge on atoms in molecules and evaluate Lewis structures on the basis of formal charge.

·  Describe the shapes of simple covalently bonded molecules using VSEPR theory.

·  Use bond dipoles to predict molecular dipoles.

·  Define dipole and compare the strengths of intermolecular forces based on dipole moments.

·  Describe hybrid orbitals and use hybridization theory to explain the bond angles in compounds.

·  Differentiate sigma and pi bonding, and saturated and unsaturated carbon compounds.

·  Define, explain, and give examples of isomerism.

·  Use molecular orbital theory to discuss bonding in diatomic molecules

·  Determine bond order and correlate bond order, bond energy, and bond length.
