Molecular modeling is primarily a tool for calculating the energy of a given molecular structure. Thus, the first step in designing a molecular modeling investigation is to define the problem as one involving a structure-energy relationship. There are two conceptually different ways of thinking about energy.
The molecular geometry describes the  arrangement of the atoms only and not the lone pairs of electrons.  If there are no lone pairs in the molecule, then the overall  geometry and the molecular geometry are the same.
