Unit 4 Chemical Bonding

Unit Objectives:

At the completion of this unit, students will be able to

1. Identify metallic bonds and how they account for the properties of metals.

2. Compare and contrast ionic and covalent bonds addressing the nature of the attraction between bonded atoms, the placement of bonding electrons, the directionality of each bond, and the polarity of each bond.

3. Draw Lewis dot structures for ionic compounds and simple molecules.

4. Use VSEPR (valence-shell electron-pair repulsion) Theory to predict the molecular geometry and polarity of molecules.

5. Name and write the chemical formulas for ionic compounds, including those with polyatomic ions, as well as molecular compounds.
