Journal Entry:

Draw Lewis structure for NI₃ and determine electron domains around central atom, electron geometry, number of lone pairs on central atom, molecular geometry, bond angles, polarity and hybridization.

Learning Intentions

• You will learn how to apply concepts from Lewis structures on released FRQs. 

• You will learn how to determine shape of a molecule based on its Lewis structure.

• You will learn how to determine electron domains on a molecule to identify electron geometry, molecular geometry, bond angles and polarity.

• You will learn what hybridization is and how it applies to bonding in a molecule.

Closing Task:

You can draw Lewis structures and analyze geometry and bond angles. 

Content Standards being covered:

The localized electron bonding model describes and predicts molecular geometry using Lewis diagrams and the VSEPR model. (EK 2.C.4)

Students are able to use Lewis diagrams and VSEPR to predict the geometry of molecules, identify hybridization and make predictions about polarity. (LO 2.21)
