Mr. Stein builds a model of a molecule out of wooden beads and pegs. He uses the model to explain the shape of the molecule. Mr. Stein uses a model because
A model illustrates the shape of the molecule and the orientation, in space, of the atoms that make up the molecule. This visualization enables the students to understand how the position of the atoms (beads) in the molecule and the different types of bonds (pegs) that join them. The interaction of the atoms (beads) and the bonds (pegs) between them affect the geometric structure of the molecule. This subsequently increases understanding of the molecule’s stereochemical outcomes of reactions.
