Today we reviewed over molecular shape and talked about electron geometry. You were given a cheat sheet to help determine the shape of a molecule as well as the electron geometry of the molecule. Ask Mrs. Spencer for a cheat sheet. The electron geometry is based on the total number of lone pairs and bonds around the central atom. The molecular shape looks at the number of lone pairs and bonds separately. We also did a gumdrop lab today.
If you missed the lab you may download and fill out he attached lab below and fill out the lab using the following link:
PhET Molecular Shapes
On this link you will find a simulation to open and in the simulation you can add lone pairs and bonds to the central purple atom. Then on the bottom left corner of the simulation to find out what the molecular and electron geometry is. On the lab packet table to fill out the shape is the molecular shape and the arrangement is the electron geometry.
