TIN

Tin è is a chemical element   in the periodic table   with the symbol Sn  and the atomic number   50. This silvery and malleable post-transition metal, which does not oxidise   easily in air and is resistant to corrosion , is used in many alloys   and for coating other metals that are more vulnerable to corrosion. Tin is obtained mainly from cassiterite , an ore   where it is present in the form of oxide , and from stannite . Tin is malleable, very ductile and silvery white in colour, with a particular crystalline structure which causes a certain squeaking sound when a bar of tin is bent (the noise   is caused by the rupturing of the crystals); and when heated, it loses its flexibility and becomes brittle. This metal is resistant to corrosion from seawater , distilled water   and drinking water , but can be attacked by strong acids , alkalis   and acid salts. Tin acts as a catalyst   in the presence of oxygen   dissolved in water, and accelerates chemical aggression. Tin binds easily with iron   and it has been used in the past to coat lead , zinc   and steel   to prevent corrosion. Containers, cans and boxes in tinplate   (tin-plated steel plate) are still widely used for the preservation of food, a use which covers most of the world market for metallic tin. In addition to the metallic form many different organic and inorganic compounds of tin(IV) are used for industrial purposes.
