Pique the Geek 20101226: Rare Earth Metals

This time we have decided to get back to geeky science and technology.  I had thought about writing about Winter Solstice celebrations through the eons, but that has passed now.  Next year for sure.

The Rare Earth Metals are a group of elements that are extremely closely related in atomic number (henceforth called Z), mass, and chemical properties.  I would wager that most folks who are not technical have never heard of them, except maybe on Mythbusters (the neodymium magnets are the strong ones that they use now and then), let alone touched one to their knowledge.

But almost everyone uses them on a daily basis, and most have indeed touched at least one.  Please come with us and let us explore these interesting and essential elements.
