Click here and download the 3D model kit to practice VSEPR shapes. You may have to update or download Java to run the program.
- electron pairs repel each other in 3D space so repulsion is minimized
- lone pairs are more repulsive than bonding pairs due to the absence of a nucleus
- double and triple bonds are treated as a single bonding pair
- only bonding pairs are used to declare the shape of the molecule around the central atom, but lone pairs may have an influence on this shape
