Elemental videos

I have a thing for the elements – the diverse atoms that make up the world. I think more of them should be better known. I’ve previously recommended Elements ($10), the best book on this realm, but the second best resource is Periodic Videos, a channel of 118 videos arranged in the form of a periodic table of the elements. Click on each box in the grid to get a free, brief, informative lesson on what is special about this unique element. — KK
