		Carl Gustav Mosander (1797-1858) turned his attention to yttria.
		Mosander has separated yttria into three earths, a colorless oxide which kept the name yttria; a yellow earth erbia, and a rosy earth terbia, containing the elements Yttrium, Terbium, and Erbium.
		Mosander's original erbia was confirmed by Marc Delafontaine in 1878 and, renamed terbia, since the name erbia was already common for Mosander's terbia.

		The next element was discovered when Mosander showed that the cerium isolated in 1803 by Berzelius was actually a mixture of cerium, lanthanum and so-called didymium (which was not actually one element, and was resolved into two in 1885).
		A number of elements were first identified by their spectroscopicemission lines: caesium and rubidium were discovered by Robert Bunsen and Gustav Kirchhoff analysing the spectrum of alkali salts.
		The 'didymium' isolated by Mosander in 1839 was shown toactually be two separate elements, praseodymium and neodymium:

	59 Praseodymium
		After he had discovered Lanthanum in 1839, in a sample of ceria, Carl Gustav Mosander (1797-1858) became convinced that there existed a third element in this earth.
		Mosander did not wanted to announce his new "discovery" prematurely, but since Theodor Scheerer (1813-1875) in Norway was analyzing gadolinite and could conclude the same thing, Mosander presented his observation at the Scandinavian Meeting of Natural Scientists in Stockholm in July 1842.
		However, Mosander did not want to change it, since he intentionally looked for a name beginning with D in order to have a symbol unlike those for other metals.

	Lanthanum Summary - Lanthanum Information
		A key discovery in this hunt was made in 1839 by the Swedish chemist and mineralogist Carl Gustav Mosander.
		Mosander was working with ceria, one of the two major fractions of a very complex rare-earth mineral known as ytterite.
		Mosander found that by heating ceria and treating the product with nitric acid, he could produce an entirely new substance.

	Terbium Summary - Terbium Information
		Credit for the discovery of terbium is usually given to the Swedish chemist Carl Gustav Mosander.
		Mosander spent many years analyzing an unusual fl rock found in 1787 near the town of Ytterby, Sweden, by a lieutenant in the Swedish army named Carl Axel Arrhenius (1757-1824).
		Mosander identified one of those new elements in 1843 and suggested the name terbium for it in honor of the town of Ytterby.

		Mosander believed that it contained an element, which he called 'didymium' (ie, twin) because it always occurred together with lanthanum.
		In 1885, Carl Auer von Welsbach managed to separate this didymium into two further elements, one of which he called 'the new twin' (see neodymium) and the other one 'praseodymium' because of the greenish colour of its oxide.
		Promethium was long sought-after, and with the implementation of the periodic table it already had its place as element 61 in the row of the rare-earth metals.

		Cerium was discovered in 1839 by the Swedish chemist Carl Gustav Mosander.
		Mosander was studying a new rock that had been found outside the town of Bastnas, Sweden, a rock from which six other elements were also to be discovered eventually.

		In 1842, Gustav Mosander separated yttria, found in the mineral gadolinite, into three fractions which he called yttria, erbia, and terbia.
		After 1860, Mosander’s terbia was known as erbia, and after 1877, the earlier known erbia became terbia.
		The erbia of this period was later shown to consist of five oxides, now known as erbia, scandia, holmia, thulia and ytterbia.

		A few years after didymium was discovered, Austrian chemist Carl Auer (Baron von Welsbach) (1858-1929) made a correction to Mosander's research.

		It was discovered by the Swedish pharmacist and chemist Carl Wilhelm Scheele in 1774 and it was first isolated by the British chemist Humphry Davy in 1808.
		In 1842, Mosander separated his lanthanium sample into two oxides; for one of these he retained the name lanthanum and for the other he gave the name didymium (or twin).
		It was discovered by the Swedish surgeon and chemist Carl Gustav Mosander in 1841, who called it didymium (or twin) because of its similarity to lanthanium which he had previously discovered two years earlier.

		The name of Carl Auer, Freiherr von Welsbach (1858-1921), usually called Auer von Welsbach, is closely associated with the rare earths.
		Carl Gustav Mosander (1797-1858), Berzelius' assistant at Uppsala, prepared pure Ce in 1827, and in 1839 separated La from it.
		Then he separated a substance with a rose-colored oxide from La and called it didymium, from the Greek "didymos" for twin, as it was a twin to La. He discovered Y, Tb and Er in 1843.

		Young Carl Lwig brought a new chemical element he had concocted at home during his summer break.
		Carl Gustav Mosander and others saw the possibility that their samples of yttria and ceria were not absolutely pure, so they set out to look for the impurities.
		In 1839, for example, Mosander obtained some cerium nitrate and treated it with dilute nitric acid.
