This lesson would typically take two days in class
Your goal for the end of this lesson is to be able to:
Identify the VSEPR shape, general formula & angles within a molecule that follows the octet rule (with the exception of including Boron & Hydrogen).
Draw simple compounds in 3D using VSEPR shapes including molecules with up to three central atoms
Watch the lesson video which highlights important information, and works through a selection of practice problems (note that the full notes key can be found on our Bonding unit home page). Pause the video as needed to ensure your notes have a complete set of examples and you understand the steps taken to solve the problems presented.
Complete all but polarity
You may wish to use the PHET simulation below to see the shapes in 3D as an alternative to molecular model kits. This is a great way to help understand the spatial piece of VSEPR, as well as to check answers.
Build each molecule using the PHET simulation. If you are unable to (because of atom limitations) do your best on paper using what you've learned from other molecules.
Check your work in RED for this assignment
You may need to update your Java platform. You can do so from here.
If you have updated your Java & downloaded the simulation to your computer, but are still unable to open it, find the download in your documents (Finder for Mac), right click, and select open.
For more troubleshooting tips, see PhET's help page here.
