Barium - Periodic Table of Videos
The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about element number 56. Barium meals (barium sulfate, not toxic barium) are among the topics in our video about the element barium. Learn all about barium in this lesson.
Despite the fact that it is a heavy element, barium is surprisingly abundant in the Earth’s crust. It is even more abundant than common elements such as carbon, sulfur and zinc.
