Procedure: Open the internet browser and enter the

Procedure:

• Open the internet browser and enter the address: Lewis structures and molecular Geometry
• If you are using the IE explorer browser, the click on run and the simulation will start. If you are using chrome. Safari, or Firefox, you may have to download the file first.

Directions: In these directions, “attached groups” Include lone pairs, single, double, or triple bonds.

1. Identify substances to which “Molecular geometry” applies

2. Explain

a. What seem to be the basic model for how groups are arranged?

b. What appears to be the major differences between “lone pairs” and the other items that can be attached to the central atom?

c. What is the main difference between the Molecular Geometry and the Electron Geometry?

3. Explore what molecules you can build. Then, read the questions below and design one table to organize your discoveries.

a. What are the combinations of attached groups atoms or lone pairs you can add to a central atom?
