Atomic Structure and Chemical Interactions
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 to visualize the number of valence electrons, students discover that the column of the Periodic Table (chemical family) that the element is placed in is related to the element’s number of outer shell electrons. They also discover that the row of the Periodic Table in which the element is placed is related to the element’s total number of electron shells and that the total number of electrons in the outer shell of a chemical compound is a multiple of eight.

Scientific Concepts
• There are more than 115 chemical elements that combine in a multitude of ways to produce compounds with different characteristic properties.
• Elements have characteristic physical and chemical properties. Substances often are placed in categories or groups if they react in similar ways; metals are an example of such a group.

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 #111Flame Test Spectroscopy
In this activity, students observe the color emitted when various metallic elements are heated in a flame. They then view the flame through a spectroscope and observe the spectral lines of the emission spectra of each of these elements.

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 #140Orbitals of the Atom Model
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...
