Tin

Tin is a chemical element with the symbol Sn (from Latin stannum) and atomic number 50. Tin is a silvery metal that characteristicly has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent the so called quot;tin cryquot; can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium and frozen mercury.
