Draw the Lewis structure for CH₂Cl₂ and NO₃^-

Learning Intentions

• You will learn structure of covalent bonding and how to draw Lewis structures to represent.

• You will learn properties of covalent bonding based on the structure.

• You will learn what formal charge is and how it is used to determine best structure for a molecule.

• You will learn what the VSEPR Theory is and how it influences geometry and shape of molecules.

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

Closing Task:

You can determine the shape of a molecule based on its Lewis Structure.
