Element Tin

Tin ElementIt 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 “tin cry” can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium and frozen mercury.
Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the “tin cry” can be heard from the twinning of the crystals.
