Chemical Elements
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol ''Z'') – all atoms with the same atomic number are atoms of the same element. Almost all of the baryonic matter of the universe is composed of chemical elements (among rare exceptions are neutron stars). When different elements undergo chemical reactions, atoms are rearranged into new compounds held together by chemical bonds. Only a minority of elements, such as silver and gold, are found uncombined as relatively pure native element minerals. Nearly all other naturally occurring elements occur in the Earth as compounds or mixtures. Air is primarily a mixture ...

Uppsala University Alumni
Uppsala (, or all ending in , ; archaically spelled ''Upsala'') is the county seat of Uppsala County and the fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located north of the capital Stockholm it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical centre of Sweden, being the seat of the Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its greatest extent. Today it serves as the residence of the Governor of Uppsala County. Founded in 1477, Uppsala University is the oldest centre of higher education in Scandinavi ...

18th-century Swedish Chemists
The 18th century lasted from January 1, 1701 (Roman numerals, MDCCI) to December 31, 1800 (Roman numerals, MDCCC). During the 18th century, elements of Age of Enlightenment, Enlightenment thinking culminated in the American Revolution, American, French Revolution, French, and Haitian Revolution, Haitian Revolutions. During the century, History of slavery, slave trading and human trafficking expanded across the shores of the Atlantic Ocean, Atlantic, while declining in Russian Empire, Russia, Qing dynasty, China, and Joseon, Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that Proslavery, supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in Society, human society and the Natural environment, environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th cen ...

Finland
Finland ( fi, Suomi ; sv, Finland ), officially the Republic of Finland (; ), is a Nordic country in Northern Europe. It shares land borders with Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland across Estonia to the south. Finland covers an area of with a population of 5.6 million. Helsinki is the capital and largest city, forming a larger metropolitan area with the neighbouring cities of Espoo, Kauniainen, and Vantaa. The vast majority of the population are ethnic Finns. Finnish, alongside Swedish, are the official languages. Swedish is the native language of 5.2% of the population. Finland's climate varies from humid continental in the south to the boreal in the north. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes. Finland was first inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several differ ...

Falun
Falun () is a city and the seat of Falun Municipality in Dalarna County, Sweden, with 37,291 inhabitants in 2010. It is also the capital of Dalarna County. Falun forms, together with Borlänge, a metropolitan area with just over 100,000 inhabitants. Falun was originally famous for its copper mine, and is today an important service and industrial city even though the mine is closed (since 1992). Faluån is a river, flowing through the city, separating it into two sides. Falu copper mine is located on one of the sides which during many centuries was one of Sweden's main business. This side of the river was usually called "the mining side", where not many plants grew due to the toxic smoke which contaminated the soil. On the other side of the river, where the smoke did not reach, set many large villas, which made this side to be called "the delightful side". The centre of Falun consists of classical pedestrian streets with small shops. In 1998, the city reclaimed the award of "the ...

Ytterby
Ytterby () is a village on the Swedish island of Resarö, in Vaxholm Municipality in the Stockholm archipelago. Today the residential area is dominated by suburban homes. The name of the village translates to "outer village". Ytterby is perhaps most famous for being the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, while four more elements were first discovered there. Mine Quartz was mined in the area beginning in the 1600s for the ironworks in Uppland. Feldspar was mined for local porcelain manufacture, such as Gustavsberg, and the porcelain trade with Britain and Poland. The mine is likely the first feldspar mine in Sweden, starting in 1790. Feldspar mining was likely sporadic and based on manufacture demand. This demand took off in the 1860s, leading to deeper mining efforts at Ytterby. The mine became one of the most productive quartz and feldspar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tantalum Element
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as ''tantalium'', it is named after Tantalus, a villain in Greek mythology. Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as components of strong high-melting-point alloys. It is a group 5 element, along with vanadium and niobium, and it always occurs in geologic sources together with the chemically similar niobium, mainly in the mineral groups tantalite, columbite and coltan. The chemical inertness and very high melting point of tantalum make it valuable for laboratory and industrial equipment such as reaction vessels and vacuum furnaces. It is used in tantalum capacitors for electronic equipment such as computers. Tantalum is considered a technology-critical element by the European Commission. History Tantalum was discovered in Sweden in 1802 by Anders Ekeber ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
