Sublevels of the Atom Models (Quantum Models)
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.

Kit #110RFamilies of ElementsIn this activity students combine different ratios of several chemical solutions and observe similarities and differences in the appearance and amount of precipitate formed. Students then use their results to determine which elements are in the same family of elements and to predict the chemical formulae for the precipitates.

Kit #109SPeriodic Table
This kit contains two activities. In Activity 1, students compare pre-selected data on physical and chemical properties of 14 elements and sort the elements into groups based on common properties. They then compare their classifications with groups - or families - of elements as defined by scientists. In Activity 2, students are introduced to the Periodic Table...

Kit #141Atomic Structure
This activity extends student understanding of the arrangement of the Periodic Table of Elements. Clearly illustrated cards allow students to view important attributes of atoms of selected elements and to famil- iarize themselves with diagrams of atoms and the relationships of the diagrams to the physical attributes. Using the planetary models on the cards...

Kit #145NAtom Modeling: Structure, Valence, & Bonding
During the three investigations in this kit, students explore the structure of atoms and how this influences the properties of elements. Although atoms cannot be chemically split, there are smaller subatomic particles within each atom. Using an innovative model, students discover the basic arrangement of protons, neutrons, and electrons in atoms of a given...
