Hunting the Elements

Did you catch the NOVA Science program Hunting the Elements last week? I learned that calcium is really a silver-colored metal. Who knew? It combines with phosphate in bone and carbonate in sea shells to get that familiar white color. If you want to see metallic calcium as well as calcium in different compounds, check out this University of Nottingham video on calcium.
And for more little known facts on elements, check out the Hunting the Elements PBS link.
There is also a "Name That Element" game to test your chemistry knowledge. A different question is posted every day. Try it!
