Molecular Model Set – Sodium Chloride (Open Type – 36 Atoms) This molecular model set illustrates the crystal structure of Sodium Chloride (NaCl) in an open lattice arrangement with 36 atoms. It effectively demonstrates the three-dimensional ionic bonding between sodium (Na⁺) and chloride (Cl⁻) ions in a cubic crystal system. The open design provides a clear view of ion positioning, coordination number, and the repeating lattice pattern. Constructed with high-quality, color-coded spheres and connectors, the model ensures easy identification of different ions. It is highly suitable for classroom demonstrations and laboratory use in schools and colleges. This model helps students gain a better understanding of ionic structures, crystal geometry, and solid-state chemistry through hands-on learning.
