Tin
A pure metallic element, listed on the periodic table as Sn (an abbreviation of Stannum, which is Latin for tin). Tin resists oxidization and corrosion, so it is commonly used in metal jewelry components. It is found in alloys such as bronze or genuine pewter. Tin is also used as an anti-corrosion coating over steel, in solder and in some batteries.
