This specific link to TED-Ed shows a periodic table, where every single element has a video link! The videos are from the University of Nottingham and all subtitled, varying in length and type of content. Randomly, I watched the videos on Mercury, Molybdenum and Oxygen. Molybdenum’s was only about a minute long, Oxygen was 6 minutes. They were all very informative, with Mercury and Oxygen having some “fun” science being shown in them so obviously it will all depend on which elements can have more visual content.
But, if you ever need to start off a bit of research on an element, or to prepare a lesson on one (especially a rarer one), this is the perfect starting location. Where else would you learn the meaning behind Mad as a Hatter?
