Gives a better insight to students into the three dimensional aspects of molecules and chemical compounds. The sets consists of colored plastic balls in different diameters and follows a universal color code in representing various elements. The balls have one or more holes and may be inter-connected to each other by white plastic unions that represent valency bonds and the structures so formed represent molecules or compounds.
