house ( /t?n/) is a chemical fragment with the symbol Sn (La sack: stannum) and atomic keep protrude 50. It is a primary(prenominal) throng coat in group 14 of the semestral table. Tin shows chemical similarity to both b arraying group 14 elements, germanium and lead and has two realistic oxidization states, +2 and the slightly more fixed +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 chiefly 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. by and by 600 BC stark(a) argentiferous bathroom was produced. Pewter, which is an alloy of 85% to 90% tin with the remainder commonly consisting of copper, antimony and lead, was used for silver medal from the dye Age until the 20th century. In modern quantify 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 diet 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 silvery-white metal. When a bar of tin i s bent, a crackling profound known as the t! in holler out can be heard due to the twinning of the crystals.[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
