In 1864, Dimitri Mendeleev published the first periodic table that organized all the known elements in the world. This tool was groundbreaking for many reasons–including the fact that Mendeleev planned with incredible foresight, leaving space for any new elements that would be discovered beyond his time.  The history of the periodic table is fascinating, but If you’ve ever taken a chemistry class, you know that memorizing those elements and understanding their properties can be difficult! To help provide a refresher and a study aid of sorts, TED-Ed collaborated with Brady Haran, best known for his YouTube channel Numberphile and his extensive video coverage of the periodic table, to create a clickable periodic table with videos on every element.
