The wave mechanical theory of atomic structure is mathematical, abstract and often confusing to students. The model students build in this activity helps them more easily visualize and better understand aspects of the wave mechanical theory. Using specialty designed components, students assemble their own spatial 3-D models. The models demonstrate the position and number of electrons along the x, y and z axes and the orbital configurations of the sublevels of the major energy levels. As students assemble the models, they review the four quantum numbers and Pauli’s Exclusion Principle. They also identify the number and position of electrons in various atoms. Students construct and compare atom models of several common elements. This illustrates and reinforces how atoms of elements within a family on the Periodic Table share similarities in their electron configurations.
