  • Tin Wikipedia

    Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically 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 “tin cry” can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium, and frozen mercury.
