Unit 2: Molecular and Ionic Compound Structure and Properties

- Atoms or ions bond due to interactions between them, forming molecules.
- Molecular compounds are arranged based on Lewis diagrams and Valence Shell Electron Pair Repulsion (VSEPR) theory.

- Represent chemical phenomena using appropriate graphing techniques, including correct scale and units.
- Represent chemical substances or phenomena with appropriate diagrams or models.
- Explain the connection between particulate-level and macroscopic properties of a substance using models and representations.
- Make a scientific claim.
- Support a claim with evidence from representations of models at the particulate level, such as the structure of atoms and/or molecules.

Students will score a 3 or higher on the Unit 2 Progress check using the AP scoring scale: 

72-100% = 5

58-71% = 4

42-57% = 3

27-41% = 2

0-26% = 1
