Tin - Wikipedia

2019-5-13 · Tin is a chemical element with the syol Sn (from Latin: stannum) and atomic nuer 50. Tin is a silvery white metal that characteristicly has a faint yellow hue due to slight oxidation. 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
