Molecular Geometry The molecular geometry of a molecule describes the three-dimensional shape of just the atoms. This is in contrast to the electronic geometry, which describes the shape of all electron regions. In order to determine the molecular geometry of a molecule, one must first determine the electronic geometry by drawing the Lewis structure. Part A What is the molecular geometry of NH_3? Part B What is the molecular geometry of CO_2? Part C What is the molecular geometry of H_2O?
