A silvery malleable metallic element that resists corrosion.
Tin: the essentials. Ordinary tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. Due to the breaking of these crystals, a tin cry is heard when a bar is bent. The element has two allotropic forms. On warming, grey, or α-tin, with a cubic structure, changes at 13.2°C into white, or β-tin, the ordinary form of the metal. White tin has a tetragonal structure. When tin is cooled below 13.2°C, it changes slowly from white to grey. Ordinary tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline structure.

Sn-a silvery malleable metallic element that resists corrosion; used in many alloys and to coat other metals to prevent corrosion; obtained chiefly from cassiterite where it occurs as tin oxide. atomic number 50, tin. tin foil, tinfoil-foil made of tin or an alloy of tin and lead.  .sn is the Internet country code top-level domain (ccTLD) for Senegal. The following 2nd level domains are available for third-level domain name registration:  tin, Sn, atomic number 50 (noun). a silvery malleable metallic element that resists corrosion; used in many alloys and to coat other metals to prevent corrosion; obtained chiefly from cassiterite where it occurs as tin oxide. see more on Definitions.net » Tin resists corrosion from water, but can be attacked by acids and alkalis. Tin can be highly polished and is used as a protective coat for other metals. In this case a protective oxide layer prevents further oxidation. Cassiterite (SnO 2), the tin oxide form of tin, was most likely the original source of tin in ancient times. Other forms of tin ores are less abundant sulfides such as stannite that require a more involved smelting process. Tin is never found as the free element. most important tin ore is cassiterite (tin oxide, SnO 2). Most of the world's supply comes from Malaya, Bolivia, Indonesia, Zaire, Thailand, and Nigeria. Cornwall in England was famous for its tin mines. On warming, grey, or α-tin, with a cubic structure, changes at 13.2°C into white, or β-tin, the ordinary form of the metal. White tin has a tetragonal structure. When tin is cooled below 13.2°C, it changes slowly from white to grey. Tin is a chemical element with the symbol Sn (for Latin: stannum) and atomic number 50. It is a main group metal in group 14 of the periodic table. Tin shows a chemical similarity to both neighboring group-14 elements, germanium and lead, and has two possible oxidation states, +2 and the slightly more stable +4. Cassiterite (SnO 2), the tin oxide form of tin, was most likely the original source of tin in ancient times. Other forms of tin ores are less abundant sulfides such as stannite that require a more involved smelting process. The Strong Name tool (Sn.exe) helps sign assemblies with strong names. Sn.exe provides options for key management, signature generation, and signature verification. For more information on strong naming and strong-named assemblies, see Strong-Named Assemblies and How to: Sign an Assembly with a Strong Name. Sn.exe computes the token by using a hash function from the public key. To save space, the common language runtime stores public key tokens in the manifest as part of a reference to another assembly when it records a dependency to an assembly that has a strong name.
