Molecular Geometry with Balloons
Background Molecular geometry can be tricky for students to grasp. Two-dimensional representations of molecular geometries predicted by the valence-shell electron-pair repulsion (VSEPR) model can be difficult to comprehend. Three-dimensional models, however, give students the opportunity to view and manipulate models as needed, making molecular geometry much easier to understand. In this activity, each balloon represents […]
