Unit 4: Bonding

Unit Objectives: At the completion of this Bonding unit, 

1. I can identify metallic bonds and how they account for the properties of metals. (CK12 Section 8.10)

2. I can 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. (CK12 Sections 8.3, 8.4, 8.6, 9.2, 9.4)

3. I can translate among representations (formulas, Lewis structures, ball-and-stick, and space-filling models) of macroscopic, atomic-molecular, and symbolic levels of matter.

4. I can draw Lewis dot structures for simple molecules and ionic compounds, including ones with polyatomic ions, showing the direction of polarity where applicable. (CK12 Section 9.5)

5. I can use VSEPR (valence-shell electron-pair repulsion) theory to predict the molecular geometry of molecules and polyatomic ions. (CK12 Section 9.13)

6. I can name and write chemical formulas for ionic compounds, including those with polyatomic ions, and molecular compounds. (CK12 Sections 7.7, 7.8, 7.9, 7.10, 7.11)

7. I can calculate the percent composition of compounds. (CK12 Section 10.10)

8. I can determine the empirical and molecular formulas of ionic and molecular compounds. (CK12 Sections 10.12, 10.13)
