AP Chemistry

Standard(s):

Intramolecular Force and Potential Energy

SAP-3: Atoms or ions bond due to interactions between them, forming molecules.

SAP-3.B: Represent the relationship between potential energy and distance between atoms, based on factors that influence the interaction strength.

SAP-3.B.3: Coulomb's law can be used to understand the strength of interactions between cations and anions.

Lewis Diagrams

SAP-4: Molecular compounds are arranged based on Lewis diagrams and Valence Shell Electron Pair Repulsion (VSEPR) theory.

SAP-4.A.1: Lewis diagrams can be constructed according to an established set of principles.

Resonance and Formal Charge

SAP-4.B.: Represent a molecule with a Lewis diagram that accounts for resonance between equivalent structures or that uses formal charge to select between nonequivalent structures.

Learning Target:

I can learn about building Lewis diagrams.

I can learn about VSEPR Theory and hybridization.

I can learn about resonance and formal charge in molecular compounds.

Success Criteria:

I can learn how to build and describe different Lewis diagrams following set principles and valence shell information about different atoms.

I can apply V.S.E.P.R. Theory when naming shapes and angles based on the valence shell electrons and the number of atoms present in a particular compounds.

I can learn and focus on application of resonance, formal charge, and hybridization in relation to the structure of a molecule and its overall behavior.

Instructional Strategies:

Opening (I do): 

Work Session (explain clearly the We Do and You Do portions):

     We Do:  

1. Continue with bonding with Chapter 8 and Chapter 9 PowerPoints.
2. Watch YouTube video on Hybrid Orbitals explained - Valence Bond Theory (Crash Course Academy)

     You Do:

1. Work on lab write-ups.
2. Finish up notes on Chapter 9 with hybridization and orbitals.
3. Practice for Unit #2 Test.

Closing (We Check):

1. Continue working on your textbook problems and finish them by Monday, September 14th before the Unit #2 Test on MCQs and then FRQs on Tuesday, September 15th!

Differentiation Strategies:

Individual work today with notes from the teacher and the PowerPoint.

Partner work on the worksheet practice.

Formative/Summative

Assessment(s): (We Check)

Completing the worksheet is formative. 

Completing the book problems, lab write-up, and future unit test will be summative.

Assignment(s):

1. Continue working on your Unit #2 ECQs out of the textbook.
2. Unit #2 Test will be on Monday, September 14th (MCQs) and Tuesday, September 15th (2 FRQs).
