Molecular Geometry and Bonding Theories

Molecular Geometry and Bonding Theories. The properties of a molecule depend on its shape and and the nature of its bonds. In this unit, we will discuss three models. . (1) a model for the geometry of molecules . -- valence-shell electron-pair repulsion (VSEPR) theory .
