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.
Molecular geometry is the three-dimensional shape of a molecule. To determine molecular geometry, first find the number of electron domains surrounding the molecule's central atom. An electron domain may come in four forms: a single bond, double bond, triple bond, or unbonded electron pair.Each is one electron domain.here are two possible shapes: trigonal planar and bent. To find out which it is, determine how many of the electron domains you counted around its central atom are made up of bonds and which--if any--of unbonded electron pairs. If all three are made up of bonds, the molecular geometry is trigonal planar.
