An Animated Timeline Tracing the Discovery of Chemical Elements Year by Year

EmperorTigerstar created an animated timeline tracing the history of chemical elements, from classical elements and alchemy to Mendeleev’s 1869 periodic table and later discoveries. The creator notes that some discovery dates are uncertain and includes selected substances once mistaken for elements to illustrate how our understanding of chemistry evolved.

The history of humanity’s scientific discovery of the elements from the classical elements to alchemy to the modern periodic table.
