Cosmically, tin is a product of neutron absorption. What's in a name? Where more than one isotope exists, the value given is the abundance weighted average. Omissions? Bronzes were common in early Mesopotamia, the Indus valley, Egypt, Crete, Israel, and Peru. For density in lb/ft 3, multiply lb/in. It is a soft, silvery white metal with a bluish tinge, known to the ancients in bronze, an alloy with copper. The major sources are alluvial deposits, averaging about 0.01 percent tin. Some of the more commercially important stannous compounds are stannous chloride, SnCl2, used in tin galvanizing and as a reducing agent in the manufacture of polymers and dyes; stannous oxide, SnO, employed in making tin salts for chemical reagents and for plating; and stannous fluoride, SnF2, an active ingredient in toothpastes. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V. This free density calculator determines any of the three variables in the density equation given the other two. White tin has a body-centred tetragonal crystal structure, and gray tin has a face-centred cubic structure. Bronzes, which are copper–tin alloys, were used by humans in prehistory long before pure tin metal itself was isolated. Elemental tin is readily oxidized to the dipositive ion in acidic solution, but this Sn2+ ion is converted to the Sn4+ ion by many mild oxidizing agents, including elemental oxygen. In the cosmos there are 1.33 atoms of tin per 1 × 106 atoms of silicon, an abundance roughly equal to that of niobium, ruthenium, neodymium, or platinum. Group Name: none. Group Number: 14. Our editors will review what you’ve submitted and determine whether to revise the article. Tin, a chemical element belonging to the carbon family, Group 14 (IVa) of the periodic table. Density (g cm −3) Density is the mass of a substance that would fill 1 cm 3 at room temperature. Tin can form a bond with carbon, as in the more than 500 known organotin compounds. Density is defined as the mass per unit volume. Maybe add your school logo, work team or anything else to make your paper look cool? Articles from Britannica Encyclopedias for elementary and high school students. Element Classification: Metal. Updates? The density of a solid varies with temperature and pressure and is similar to a liquid and is generally less pronounced. Tin is pronounced as TIN. The gray form changes to the white above 13.2 °C (55.8 °F), rapidly at temperatures above 100 °C (212 °F); the reverse transformation, called tin pest, occurs at low temperatures and seriously hampers the use of the metal in very cold regions. When bent, tin makes an eerie, crackling “cry” as its crystals crush each other. As the world silver market began to decline in the 1880s and early ’90s, mining operations began shifting to tin, which is found in association with silver,…, …in a few regions, and tin, particularly restricted in its distribution, was found only in eastern Portugal, Sardinia, Tuscany, Cornwall, the Isles of Scilly, and the Bohemian Ore Mountains. To see how density of materials is calculated, click here.If you find this … 3 by 1728; for g/cm 3, multiply density in lb/in. Relative atomic mass The mass of an atom relative to that of carbon-12.

Tin: 7.31 g/cm 3: Einsteinium: N/A: Nitrogen: 1.251 g/l: Titanium: 4.507 g/cm 3: Erbium: 9.066 g/cm 3: Nobelium: N/A: Tungsten: 19.25 g/cm 3: Europium: 5.244 g/cm 3: Oganesson: N/A: Uranium: 19.05 g/cm 3: Fermium: N/A: Osmium: 22.59 g/cm 3: Vanadium: 6.11 g/cm 3: Flerovium: N/A: Oxygen: 1.429 g/l: Xenon: 5.9 g/l: Fluorine: 1.696 g/l: Palladium: 12.023 g/cm 3: Ytterbium: 6.57 g/cm 3: Francium: N/A: … It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. Lode deposits, containing up to 4 percent, are found in Bolivia and Cornwall. The colour of pure tin is retained during exposure because a thin, invisible, protective film of stannic oxide is formed spontaneously by reaction with the oxygen of the air. Period Number: 5. Gelson Luz is a Mechanical Engineer, expert in welding and passionate about materials. Several processes have been devised for reclaiming the metal from scrap tin or tin-plated articles. Titanium nitride (TiN; sometimes known as Tinite) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties. Let us know if you have suggestions to improve this article (requires login). Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. Tin is a post-transition metal in group 14 of the periodic table. Organotin stabilizers are used to prevent changes in polyvinyl chloride upon exposure to light and heat. Tin: Sn: 50: 7.43 g/cc: Manganese: Mn: 25: 7.52 g/cc: Samarium: Sm: 62: 7.874 g/cc: Iron: Fe: … In this quiz you’ll be shown all 118 chemical symbols, and you’ll need to choose the name of the chemical element that each one represents. (For a full treatment of tin mining, refining, and recovery, see tin processing.). 3 by 27679.9 Metal / Element or Alloy Density Density Please select which sections you would like to print: Corrections? 3 by 27.68; for kg/m 3, multiply density in lb/in. Tin-plating of iron protects the latter from corrosion; tin piping and valves maintain purity in water and beverages; molten tin is the base for (float) plate-glass production.
