The 4 x 4 x 4 Lattice contains 64 ions (32 Sodium and 32 Chlorine) and the 3 x 3 x 3 Lattice contains 27 ions (13 of 1 type of ion and 14 of the other.) Lattices do not include water molecules, which are available, if required, in the magnetic water molecule kits.
3D Molecular Designs Magnetic Sodium Chloride Models will help students to understand the structure and properties of ionic compounds.
Each ion has 6 embedded magnets to simulate ionic bonding.
The models will help students gain an understanding of: Ionic structure and bonding
The cubic nature of salt crystals, Efficient lattice packing, High melting temperature, and Brittleness Cleavage planes.
