Periodic Table Timeline

Interactive 3D simulation of the history of chemistry: watch the periodic table fill in element by element from antiquity to the synthetic superheavy era, including Mendeleev's 1869 predicted gaps resolving into gallium, scandium and germanium.

The periodic table wasn't handed down complete — it was assembled over three thousand years, tile by tile, as chemists isolated one new element after another. This simulation lays every element out at its true periodic-table position and reveals each one the instant it was actually discovered, from Bronze-Age metals through Mendeleev's famously predicted gaps to the synthetic superheavy elements made in particle accelerators after 1945. Scrub the timeline or hit play to watch three thousand years of chemistry unfold across the grid.
