Interactive Periodic Table
From the TED-Ed group, this interactive periodic table of elements features videos on each element. There are also links to “Full Lessons” for each. Once in this area, visitors can take quizzes, find links to more resources, and contribute to open or guided discussions.
Additionally, there are buttons at the bottom of the periodic table that make it simple to limit to groups of elements, such as the “Alkali Metals” and the “Rare Earth Metals”.
