keister ( /t?n/) is a chemical fragment with the symbol Sn (La sack: stannum) and atomic keep big money 50. It is a primary(prenominal) throng aluminiferous element in group 14 of the semestral table. Tin shows chemical similarity to both b orderlinessing group 14 elements, germanium and lead and has two doable oxidization states, +2 and the slightly more unchangeable +4. Tin is the forty-ninth most abundant element and has, with 10 stable isotopes, the immensest number of stable isotopes in the periodic table. Tin is obtained in the main from the mineral cassiterite, where it occurs as keister dioxide, SnO2. This silvery, malleable poor metal is not easily oxidized in air and is employ to pelage other metals to prevent corrosion. The first alloy, used in large scale since 3000 BC, was bronze, an alloy of give the axe and copper. aft(prenominal) 600 BC stark(a) metallic stomach was produced. Pewter, which is an alloy of 85% to 90% tin with the remainder common ly consisting of copper, antimony and lead, was used for atomic number 47 from the dye Age until the 20th century. In modern clock tin is used in many alloys, most notably tin/lead soft solders, typically containing 60% or more of tin. Another large application for tin is corrosion-resistant tin plate of steel. Because of its low toxicity, tin-plated metal is also used for forage packaging, with child(p) the name to tin cans, which are made mostly of steel.

[edit] Characteristics [edit] physical properties, allotropes, and tin pest Droplet of melted tin Tin is a malleable, ductile, and highly filmy silv ery-white metal. When a bar of tin is bent, ! a crackling profound known as the tin war cry can be heard due to the twinning of the crystallizings.[2] ?-tin (the metallic form), which exists at get on temperature and hotter, is malleable; while the ?-tin (nonmetallic form), create when tin is cooled below 13.2 °C, is brittle. It has a diamond cubic crystal structure, similar to diamond, silicon or germanium. ?-tin has no metallic properties at all. It is a dull-gray powdery real(a) with no common uses, other than a few specialized...If you deficiency to get a full essay, order it on our website: BestEssayCheap.com
