From the periodic table outward — small interactive apps to feel the shape of atoms, the texture of bonds, the geometry of reactions, and the quiet rules that make matter behave.
A spatial index of every known element — hover for the quick read, click for the full passport, recolour by property, and rotate any atom’s Bohr model.
Drop elements onto the bench, set the conditions, and watch the products form with conservation laws enforced.
A virtual burette over a virtual beaker. Drip an acid into a base and read the curve as it tips.
Type a reaction — get the coefficients, the limiting reagent, and a clean visual of what changes hands.
Walk through covalent, ionic, metallic and hydrogen bonds — each a tiny live diagram you can rotate.
