With the Cubic Unit Cell Model for Chemistry Class, students get a clear picture of the arrangement of ions in a face-centered unit cell. Use this “super-size,” versatile model to demonstrate the concept of the unit cell.
Use this “super-size” model of the sodium chloride crystal lattice to demonstrate the concept of the unit cell. Students will get a clear picture of the arrangement of ions in a face-centered unit cell, and will begin to understand the fractional contributions ions in different locations add to the total number of ions in the unit cell. Rearrange the easy-to-remove plastic spheres to create either the body-centered cubic unit cell or the simple cubic unit cell. A versatile tool for teaching crystal lattice structure! Teacher Demonstration Notes included.
