Molecular Geometry is the true shape of a molecule that takes into account differences in repulsion between lone pairs and surrounding elements.
Concept #1: Two Electron Groups
Concept #2: Three Electron Groups
The molecular geometry of a compound treats surrounding elements and lone pairs on the central element as different.
Example #1: Determine the molecular geometry for the following molecule: BCl3
Concept #3: Four Electron Groups
Example #2: Determine the molecular geometry for the following ion: NH4+
