Use the Calcium Sulphate molecular model to show the elementary structure of calcium sulphate (anhydrous) as well as other comparable crystal structures such as silicate and phosphate. The bonds of the elementary structure are identified in white so as to be clearly visible on the Calcium Sulphate model. The molecular structure of calcium ...

Use this unique model to illustrate the structure of graphite with its tightly packed carbon atoms arranged in layers. The clear plexiglass surfaces which separate the layers provide an unobstructed view of the dark carbon "atoms" and help students to understand how this arrangement explains graphite's physical properties.
