Molymod Sodium Chloride Model – Ionic Lattice Structure (NaCl)

The Molymod Sodium Chloride Model is a clear and effective teaching resource designed to illustrate the ionic crystal lattice structure of sodium chloride (NaCl). This model accurately represents the arrangement of positive sodium ions and larger negative chloride ions, helping students visualise ionic bonding and electrostatic attraction in solids.

Using the trusted Molymod system, the model clearly shows that chloride (Cl⁻) ions are larger than sodium (Na⁺) ions, reinforcing an important concept that students often find difficult when working only from diagrams. The three‑dimensional structure highlights the regular, repeating lattice formed by oppositely charged ions.

Robust, reusable, and easy to assemble, this model is ideally suited to classroom demonstrations, small‑group work, and revision activities in secondary chemistry lessons.
