Radiolab, my all-time favorite podcast, did an episode this week about some of the elements from the periodic table, including lithium, carbon, and xenon. You can hear snippets of poems about oxygen and more. The more includes dark matter, which doesn't belong in the periodic table.
It's not Radiolab's first show about the elements of the periodic table (or Mendeleev for that matter), and hopefully it won't be their last. But you don't want to miss this one.
