Modeling Molecules Introduction: You can represent a molecule two-dimensionally‚ as a structural formula or electron dot structure. Although such models are useful in certain contexts‚ they do not accurately represent bond angles between atoms or shapes of molecules. In this activity‚ you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the three-dimensional models. Materials: jelly beans
