Erbia was one of the many new elements found in a black rock discovered outside the town of Ytterby, Sweden, in 1787. Per Teodor Cleve (10 February 1840 18 June 1905) was a Swedish chemist, biologist, mineralogist and oceanographer. This was contaminated with these chemically similar elements. Cleve, P. T. (Per Teodor), 1840-1905 Title ; Close. [6], Cleve worked on the synthesis of complex chemical compounds until 1872. Per Teodor Cleve determined didymium must be made of at least two elements in 1874. [1] He was the chair of chemistry at the University of Uppsala starting in 1874. Genom mikroskopisk underskning av de fossila diatomacerna i nordtyska, danska, finlndska och svenska avlagringar skapade han en metod fr avgrande av de postglaciala avlagringarnas natur och lder. Holmium was discovered spectroscopically (1878) by Swiss chemists Jacques-Louis Soret and Marc Delafontaine and independently (1879) by Swedish chemist Per Teodor Cleve, who separated it chemically from erbium and thulium. [7], Cleve's first work was Ngra ammoniakaliska chromfreningar (Some compounds of ammonia and chromium, 1861). [3] His other contributions to chemistry include the discovery of aminonaphthalenesulfonic acids, also known as Cleve's acids. Thulium was discovered by Swedish chemist Per Teodor Cleve in 1879 by looking for impurities in the oxides of other rare earth elements (this was the same method Carl Gustaf Mosander earlier used to discover some other rare earth elements). Hans forskningsresultat angende naftalinderivaten fick grundlggande betydelse fr knnedomen om en del tjrfrgmnen. [6], Cleve visited a number of laboratories in England, France, Italy, and Switzerland in the 1860s. [12][3][13][14], Cleve discovered six forms of dichloronaphthalene and discovered aminonaphthalenesulfonic acids, which are sometimes named after him. In 1879 Cleve discovered holmium and thulium. The television host and politician Lisette Schulman was his great-granddaughter. He later became professor of general and agricultural chemistry. In 1874 he theorised that didymium was in fact two elements; this theory was confirmed in 1885 when Carl Auer von Welsbach discovered neodymium and praseodymium. Han blev hedersledamot av Royal Microscopical Society 1879, av Chemical Society 1883 och av Royal Institution i London 1904.

[2] He discovered the element holmium in 1879 by examining a sample of erbium oxide. It was independently isolated from cleveite the same year by chemists Per Teodor Cleve and Abraham Langlet in Uppsala, Sweden, who were able to The third and last daughter, Clie Brunius (born Gerda Cecilia Afrodite Cleve) (1882-1980), was a journalist.

In 1879, Lecoq de Boisbaudran isolated samarium from a sample containing didymium, leaving Carl Auer von Welsbach to separate the two remaining elements in 1885. [1] He isolated a quantity of scandium in this same year and determined its atomic weight. [4][5] Cleve's ancestors on his father's side came from western Germany and settled in Sweden in the late 18th century. prepared numerous previously-undiscovered salts of yttrium and erbium. Redan under studenttiden gnade sig han ivrigt t studiet av stvattensalgerna, utgav uppsatser och monografier ver desmidiacerna, zygnemacerna och i synnerhet ver diatomacerna. 2, C-F, Cleve, Per Teodor, f. 1840 i Nikolai, Professor, Uppsala domkyrkofrsamlings kyrkoarkiv, Dd- och begravningsbcker, SE/ULA/11632/F/11 (1902-1909), bildid: 00150928_00182, sida 179, https://sv.wikipedia.org/w/index.php?title=Per_Teodor_Cleve&oldid=48731255, Personer verksamma vid Uppsala universitet, Ledamter av Kungliga Vetenskapsakademien, Sidor med Faktamall biografi WD som har P3217 p Wikidata, Wikipediaartiklar med identifierare frn VIAF, Wikipediaartiklar med identifierare frn LCCN, Wikipediaartiklar med identifierare frn ISNI, Wikipediaartiklar med identifierare frn GND, Wikipediaartiklar med identifierare frn LIBRIS, Wikipediaartiklar med identifierare frn BNF, Wikipediaartiklar med identifierare frn BIBSYS, Wikipediaartiklar med identifierare frn kulturnav, Wikipediaartiklar med identifierare frn SBL, Creative Commons Erknnande-dela-lika 3.0 Unported, den frsta upplagans band 2 (1874) behandlar.

Later in 1878, a Swedish chemist, Per Teodor Cleve independently discovered the element holmium. [4][7], The mineral cleveite is named for Cleve. Holmium Please visit the Holmium element page for information specific to the chemical element of the periodic table. These findings were initially doubted by the scientific community. The first daughter, Astrid Maria Cleve (born 22 January 1875), became a botanist. Add Definition. In 1903, large reserves of helium were found in natural gas fields in parts of the United States, which is by far the largest supplier of the gas today. The discoveries of the many rare earth elements (aka lanthanoid) began with yttrium in 1794.

[2] He theorized in 1874 that the element didymium consisted of two elements. [1][2] In 1883, he published Kemiskt Handlexicon, which translates to Chemical Handbook. In 1879, Cleve proved that the newly discovered element scandium was an element predicted by Dmitri Mendeleev to be "eka-boron".

Notable students of Cleve include Ellen Fries (the first Swedish woman to earn a PhD) and Svante Arrhenius (a winner of the Nobel Prize). He developed a method of determining the age and order of late glacial and postglacial deposits from the types of diatom fossils in the deposits, and wrote a seminal text in the field of oceanography. By 1874, Cleve discovered that thorium was a quadrivalent element and also determined lanthanum to be trivalent. Da kurfyrst Karl Teodor som bodde i Schwetzingen forskte restaurere borgen, traff lynet borgen i 1764 og gjorde slutt p alle forsk p gjenoppbygge borgen. Studiet av de pelagiska diatomacerna frde honom in p oceanografins omrde, och frn 1893 skte han genom studiet av samtliga planktonorganismer erhlla metoder att utreda cirkulationen i oceanerna. r 1879 upptckte svenskarna Per Teodor Cleve och Lars Fredrik Nilson grundmnena erbium (Er), holmium (Ho), skandium (Sc), samt tulium (Tm). While on this mission, he discovered a number of species of spumellarians, nassellarians, and phaeodarians. Cleve, Per Cleves farfars far. Gadolin discovered a new mineral in the rock, now now known as yttria. Initially, Arrhenius helped Edlund with his work measuring the electromotive force in spark discharges, but he soon moved on to his own research. 18.41.
