![]() Later on, in 1673, British scientist Robert Boyle performed experiments on the pure element tin. This prompted the domination of tin trade in the Mediterranean Sea. Tin mining peaked between the 8th Century BCE and the 6th Century AD, specifically in England and Spain. This dramatically altered civilization, marking the beginning of our interaction with different metals and associated usage of weapons. Citizens of Ur, a city-state in ancient Mesopotamia, were likely the first people to encounter the element. Tin has been around for a long time, so we don’t know who discovered it. During this time, people used tin to make bronze, an alloy of tin (12%) and copper. We can trace the origins of tin back to the prehistoric Bronze Age period, which spanned from 3300 BCE to 1200 BCE. Tin is also found in the mineral Stannite, which is a sulfide of tin, iron and copper. The most popular ore that contains tin is known as Cassiterite (SnO 2), from which researchers generate tin by reducing it with carbon in a hot furnace. The majority of sourced tin comes from different ores, which scientists obtain from mines and natural deposits. Little tin can be found in the United States the vast majority of this tin comes from Alaska. The element tin typically appears in certain countries, including Bolivia, Indonesia, Thailand, and Nigeria. Tin only composes about 2ppm of the Earth’s crust, rendering the element relatively rare in comparison to other more abundant metals. Because of this shift, Scott’s men likely had a much more difficult time staying warm and fed-this led to their ultimate demise and the failure of their mission. The gray allotrope of tin, as discussed, is brittle and powder-like. Scientists postulate that everything from the buttons on their jackets to their tin can food containers changed from white tin to gray tin. Although Scott and his research team meticulously prepared for their journey to the South Pole, they did not anticipate the effects of the region’s cold climate on their tin-containing possessions. Robert Scott’s expedition to Antarctica provides an example of such a scenario. Tin pest can occur spontaneously under severely cold conditions. In regard to structural differences, white tin adopts a tetragonal crystalline shape, while gray tin appears cubic. They can also transition white tin back to gray tin at lower temperatures of -50☌ in a process known as “tin pest.” However, trace amounts of antimony, bismuth, copper, lead, silver, or gold, typically present in commercial tin, hinder this reaction. This process occurs rapidly at temperatures exceeding 100☌. Scientists can generate white tin, the more familiar and common form, from gray tin. While metallic β-tin remains malleable and stable at room temperature, nonmetallic α-tin appears brittle. Tin exists in two different forms, or allotropes: white (beta) and gray (alpha). Tin (Sn) has an electron configuration of 5s☤d¹⁰5p². Tin is a post-transition metal that has similarities to both germanium and lead. It lies below the semi-metal germanium, and above the metal lead. ![]() It lies between indium and the semi-metal antimony. The element tin, symbol Sn, is atomic number 50 in the periodic table. Tin changing from the beta to the alpha allotrope in cold weather is often blamed for causing Robert Scott’s Antarctica expedition to fail. Making tin crystals is one of the coolest chemistry experiments you can do.ġ0. TIn is one of the easiest metals to melt, which means it can easily be cast into different shapes and figures, like tin soldiers.ĩ. Scientists first observed the Meissner Effect, typically seen in superconductor substances, in tin crystals.Ĩ. Scholars derived the elemental symbol for tin, Sn, from the Latin term “stannum,” an alloy of lead and silver.ħ. The United States consumes more tin than any other country in the world.Ħ. Tin possesses more isotopes than any other element.ĥ. When craftsmen struggled to work with soft tin, they formed bronze by alloying tin with copper.Ĥ. The usage of tin dates back to ancient civilizations.ģ. When you bend a bar of tin, it emits a screaming sound called a “ tin cry.” This phenomenon results from the breakage of crystal lattice structures within the substance.Ģ. Tin is a malleable, silvery substance that gives off a slightly bluish tinge. We typically encounter this metal mixed, or alloyed, with other metals however, it is relatively non-reactive at room temperatures. The element Tin, located in Group 14 on the Periodic Table, falls into the post-transition metal category.
