The 3D periodic table above turns properties such as atomic weight, density and melting point into height and colour, and lets you change the temperature and discovery year to watch the elements change. Pick an element to rotate its electron shells and orbitals in 3D; each element page adds the key data and the everyday-economy story behind it, from batteries to semiconductors and rare earths. In Molecules 3D and the Labs you can rotate and even build molecules such as DNA and caffeine.
