The chemical formula of a molecule contains the chemical symbols of each element with a subscript to the right of each that indicates how many atoms of that element are present. although the chemical formula indicates the type and number of atoms included, the order that they are bonded in is not indicated. when a molecule is created in the simulation, click on the green box labeled 3d to view a model of the molecule. either space filling or ball and stick can be selected. use the phet simulation to build each molecule based on the chemical formula, then view in three dimensions to determine the order that they are bonded. match each of the given chemical formulas to the appropriate models. atom color nitrogen blue oxygen red chlorine green carbon gray (large atom) hydrogen gray (small atom)
