Element of the Day! - Monday, May 17th

Who am I? I am a very dense, silver-colored, liquid metal that is poisonous. I used to be used in thermometers and am still used in some dental amalgams (fillings). I am named after a Roman god known for speed and mobility. I am also associated with a planet. E-mail me with your answer at
Include the element's chemical symbol.
