Use the mode in the PhET simulation to go through the various types of structures that can be made by forming and breaking bonds. The coordination around the central atom can range from 0 to 6, but the geometries that are of interest arise from coordination numbers of 2 to 6. You can click the Molecule Geometry checkbox to have the geometry of the currently drawn structure displayed on screen.
After familiarizing yourself with the simulation, complete the following table that matches geometries, coordination models (notations), and structural features.
Drag the appropriate labels to their respective targets.
