Concept introduction:
A lewis dot structure is a diagram that show bonding between the atoms. A lewis dot structure is used to predict the geometry of the molecule.
A lewis dot structure is a two dimensional representation whereas a molecular structure is a three dimensional structure and many of the properties both chemical and physical are dictated by molecular structure.
Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons
Electron geometry is the shape of a molecule predicted by considering both bond electron pairs and lone pair of electrons.
According to VSEPR theory, the geometry is predicted by the minimizing the repulsions between electron-pairs in the bonds and lone-pairs of electrons. The VSEPR theory is summarized in the given table as,
