Product 12736

By: The Flinn Staff

In the Crystal Structure Chemical Bonding Laboratory Kit, students build models of cubic crystal lattice structures closest-packed arrangements. Students analyze the models to discover the total number of atoms or ions in each unit cell.

Product Details

How are atoms arranged in a metallic solid and in an ionic compound? Are the arrangements of atoms random or is there a “system” to it with regular “repeating units? In this two-part lab, students will build models of the three cubic crystal lattice structures and the closest-packed arrangements using polystyrene foam spheres and wire connectors. Students then analyze the models to determine the total number of atoms or ions in each unit cell. Includes 84 2-inch spheres, 72 1-inch spheres and wire connectors along with Teacher Notes, extensive background material and reproducible student handouts.

Super Value Kit is complete for six student groups. All materials are reusable!
