Description Contents Teacher Resources
 

Take your salt crystal lessons from 2-D to 3-D. These colorful sodium chloride ion models will help your students discover the cubic nature of salt crystals, efficient lattice packing, high melting temperature, brittleness and cleavage planes.

A valuable companion to 3D Molecular Designs’ Water Kit©, our NaCl magnetic lattice ions take salt lessons further. Each ion model has 6 embedded magnets which allows for 6:6 coordination and tight packing. Your students will explore how the positive sodium and negative chloride ions form electrostatic bonds creating a strong crystal structure. Your students will also see water molecules dissolve salt from the outer edges of the lattice.

The 4x4x4 lattice contains 64 ions (32 sodium and 32 chloride) and the 3x3x3 lattice contains 27 ions (13 of 1 type of ion and 14 of the other.) NaCl Lattice© does not include 3DMD water molecules. Water molecules are sold in Water Kits©.

Fantastic model April 7, 2015
Reviewer: George Lisensky from Beloit, WI United States  
These models are wonderful for illustrating the NaCl structure and the cleavage that occurs if you shift the ions by one position. Actual NaCl crystals do the same. We use water softener salt and have students do the experiment.

These models are one of the few molecular models that get the energetics correct. Forming a bond releases  energy but most models leave the impression that energy is required. When we first talk about bonds I pass out a pair of atoms to each student and have them experience bond formation as a kinesthetic experience. Its worth the clicking distraction to have them form bonds over and over!
