Jonah:

The old, funny National Lampoon, circa 1970, did a spoof educational comic strip with the elements of the periodic table as superheroes. It was called something like “League of the Elements.” I remember almost nothing about it except some effort to keep Hydrogen and Oxygen from getting too close to each other (they turned into a puddle of water when united), and everyone being scared of Uranium. A quick google didn’t turn this up. If anyone knows where I can find the strip, please tell me.
