Metal Alloys Simulation — Description The simulation shows a 3D hexagonal close-packed metallic lattice (6 rows × 9 columns × 3 deep) that students can orbit, zoom, and interrogate by hovering individual atoms. Three controls drive the core chemistry: ⚗ Alloy transitions the lattice from pure metal to alloy — substitutional atoms grow in at […]

Polymer and Monomer Simulation — Description The simulation Three parallel poly(ethene) chains run side by side in 3D space. Carbon atoms (grey-blue spheres) form the zigzag backbone; hydrogen atoms (smaller cream spheres) branch off each carbon. Yellow lines between the chains represent weak van der Waals forces — the intermolecular forces that hold chains together

Giant Ionic Lattice Simulation — Description The simulation shows a 5×4×4 NaCl lattice of 80 ions rendered in 3D using Three.js. Na⁺ ions appear purple and smaller, Cl⁻ ions appear green and larger, reflecting their real relative ionic radii. Yellow lines represent the electrostatic attraction between each Na⁺ and its six adjacent Cl⁻ neighbours. Students

Metallic bonding simulation What the simulation shows ⚡ Apply Voltage — electrons visibly drift toward the + terminal; sweeping light pulse reinforces directionality; teaches electrical conductivity 🔨 Apply Force — top two ion layers slide smoothly over the bottom two; a slip plane appears; cross-layer bonds disappear, showing no bond breakage; teaches malleability and ductility

Ionic bonding, Covalent bonding and Metallic bonding simulation The simulation is a three-tab interactive 3D Bohr model built in Three.js, designed for GCSE Chemistry (AQA/Edexcel/OCR/WJEC). All three bonding types are covered with consistent visual language: dark navy background, orange electron dots on thin shell rings, near-frontal camera so rings appear as circles exactly as in
