Unit Overview: In this Unit, students use The Atomsmith® Classroom and the Valence Shell Electron Pair Repulsion model (VSEPR) to predict the 3D arrangement of atoms around a nonmetallic central atom. The VSEPR model is based on the premise that molecular geometry can be predicted by minimizing the repulsion between atoms’ electron pairs (maximizing the distance between them). Understanding the simple rules of VSEPR allows students to understand the formation and construction of larger, much more complicated molecules.


When 3 electron pair orbitals repel each other, the resulting shape is called trigonal planar. (Click to Enlarge)
