Element number 50, symbol Sn, a metal (Latin, stannum) A silver white soft ductile metal occasionaly found in its native state Tin is one of the earliset known metals and was used both in its pure form as well as an alloying ingrediant by the ancients Pure tin was used by the Ancient Greeks as parts of light tight fitting armor such as shin guards (Homer's, Illiad Tin is the secondary metal in the alloy bronze and the primary metal in solder along with lead (Pb) Tin is corrosion resistant and has a very low melting point as well as an affinity for adhearing to other metals, thus tin plate, tin cans, babbit and solder Average density of tin, 7 298 g/cm3, 2637 lbs/cuin, 455 62 lbs/cuft Los Alamos National Laboratory periodic table entry tin

It is a soft, silvery white metal with a bluish tinge, employed since antiquity in the traditional form of bronze, its alloy with copper. It occurs chiefly as the dioxide (stannic oxide, SnO2) in cassiterite. Since it is nontoxic, ductile, malleable, and easily worked, it is used to plate steel cans ("tin cans") for use as food containers and to coat and plate other items. Pure tin is too weak to be used alone, but its many alloys include soft solder, pewter, bronze, and low-temperature casting alloys. It has valence 2 or 4 in compounds, including stannous chloride (used in tin galvanizing and manufacturing polymers and dyes), stannous oxide (used to make tin salts for chemical reagents and plating), stannous fluoride (used as an anticavity ingredient in toothpastes), stannic chloride (a stabilizer for perfumes and a source of other tin salts), and stannic oxide (a catalyst and a polishing powder for steel). Tin bonds with carbon to form organotin compounds, used to stabilize PVC and in biocides and fungicides
It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to form the reflective surface of mirrors, and in solder, bronze, speculum metal, and other alloys
When present in steel it is an undesirable impurity which gives rise to temper brittleness When used as a coating on steel, it has a good resistance to corrosion for many applications
