Periodic Table puzzle

While Brent was here I broke out the periodic table jigsaw puzzle.  Nothing like having fun while you learn something. 

The weather this time of year is often 'wavy'.  A period where it gets warm and snows followed by a few days of super cold.  We are currently in a relatively warm spell.  No snow but fog thick enough to coat everything in ice crystals.  Quite pretty plus the cats and I like a warm house.  Indy w/ her thick fur coat prefers sitting out on top of the snow.
