Molecular Model Set – Sodium Chloride – Open 36 Atoms

Quick answer: The Sodium Chloride 36-Atom Open Model is an expanded crystal-lattice model used to visualize NaCl’s extended structure, ionic bonding, and face-centered cubic (FCC) symmetry for crystallography and material science teaching.

This 36-atom open-format model gives students and researchers a broader spatial view of sodium chloride’s extended crystal lattice than a smaller compact model can offer. It is designed to support analysis of ionic bonding patterns and face-centered cubic (FCC) symmetry, making it a useful tool for laboratory demonstrations where a larger, more detailed lattice view helps convey how the repeating unit cell extends through the crystal.

Fuller Description

Sodium chloride is a classic teaching example of ionic bonding and crystal symmetry, and this open, 36-atom format is intended for situations where a more expansive lattice view is useful — for example, demonstrating how the FCC unit cell repeats through the structure. For institutions that also want a smaller, more compact reference model, our 27-atom open and compact NaCl models make useful companion pieces, letting students compare lattice scale and packing side by side.

Specifications

Care & Handling

• Store the 36 atom pieces in their case to keep the model complete between uses.
• Wipe components with a dry cloth; avoid harsh solvents that can degrade plastic parts.
• Check connector joints periodically for wear, given the model’s larger size.
• Keep small pieces away from young children not directly supervised during the lesson.

Frequently Asked Questions

What does the 36-atom open model show that smaller models don’t?
Its larger, open format gives a broader spatial view of how the NaCl unit cell repeats through an extended crystal lattice, which can be harder to see in a smaller compact model.

What crystal symmetry does this model demonstrate?
It demonstrates the face-centered cubic (FCC) symmetry and ionic bonding pattern characteristic of the sodium chloride crystal structure.

How is this different from the 27-atom NaCl models?
The 36-atom open model provides an expanded, larger-scale view of the lattice, while the 27-atom open and compact models are smaller reference formats. Institutions often pair them for comparison.

What level of course is this suited for?
It is designed for college and university-level crystallography and material science coursework.

What materials is the model made from?
