Why? Mel forte How can molecular shapes be pi icted using the VSEPR theory? ‘When you draw a Lewis structure for a molecule on paper, you are making a two-dimensional representa tion of the atoms. In reality however, molecules are not flat—thcy are three-dimensional. The true shape ofa molecule is important because it determines many physical and chemical properties for the substance. In this activity you will learn how to predict molecular shapes.
