Niobium - 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 niobium, a particularly friendly element.
In Greek mythology, Niobe was the daughter of Tantalus, who was the son of Zeus. If we look in the periodic table, we can find her element, niobium, just above tantalum (but the element just below tantalum is not named zeusium, it is dubnium).
