Product Overview
The Polylab Sodium Chloride – Open 36 Atoms Model Set offers an in-depth and interactive way to study the face-centered cubic (FCC) structure of sodium chloride (NaCl)—a foundational topic in solid-state chemistry. This molecular model is designed specifically for educational use, enabling students and instructors to explore the geometric arrangement and ionic interactions present in real-world salt crystals.
Accurate Representation of the NaCl Lattice
This model captures the true symmetry of the NaCl crystal by illustrating alternating sodium (Na⁺) and chloride (Cl⁻) ions arranged in a three-dimensional lattice. Unlike compact or filled models, the open 36-atom design provides clear visibility into the inner spatial relationships, allowing learners to grasp the coordination number (6:6), unit cell geometry, and lattice stability of the compound with remarkable clarity.
Engaging, Kinesthetic Learning Tool
Constructed with color-coded, durable plastic atoms and rigid connectors representing ionic bonds, the model promotes hands-on engagement, making complex chemistry topics more accessible. Students can physically build and analyze the structure, enhancing their understanding through kinesthetic and visual learning—a method proven to boost retention and comprehension.
Ideal for Diverse Educational Environments
From CBSE and ICSE boards to IGCSE, IB, and university-level chemistry, this set aligns well with academic syllabi. It also supports preparation for competitive exams like NEET and JEE, where a deep understanding of ionic bonding and crystalline solids is essential. Whether used in classroom lectures, lab sessions, or educational exhibitions, the model is an excellent visual aid to reinforce textbook theory.
Practical, Durable & Classroom-Safe
Every component in this set is manufactured from non-toxic, impact-resistant plastic, ensuring it can withstand repeated classroom handling. The model is easy to disassemble and pack back into its compact storage box, while the included instruction manual assists users in accurately replicating the NaCl lattice. It’s a resource built for long-term academic use.
Educational Versatility
This model does more than show ionic bonding. It enables instructors to delve into advanced concepts like:
- Lattice energy and electrostatic forces
- Differences between crystalline and amorphous solids
- Ionic conductivity in different states
- Packing efficiency and space filling in unit cells
Whether used for lectures, labs, peer demonstrations, or self-study, the model elevates both teaching quality and student participation.
