	Carl Gustaf Mosander Biography \| World of Chemistry
		Mosander was born in Kalmar, Sweden, on September 10, 1797.
		Eventually, Mosander became curator of minerals at the Academy and, in 1832, succeeded Berzelius as Permanent Secretary of the Academy.
		Mosander did not publish his results immediately, however, because he was convinced that yet more discoveries were to be made.

		Carl Gustaf Mosander, a student of Jöns Jakob Berzelius, identified the element cerium (named after the recently discovered asteroid Ceres, which in turn had been named after the Roman goddess of crops and wheat).
		Carl Gustaf Mosander isolated lanthanum (from the Greek lanthanein: to escape notice) and ‘didymium’ (from the Greek didumos: twin, as its properties are very similar to lanthanum).
		Carl Auer von Welsbach, in Robert Bunsen's laboratory, noticed that the rare earths displayed bright light in the burner flame and developed the lace gas mantle, which is composed of thorium oxide with small amounts of cerium oxide.

		Discovered when Mosander showed that the cerium isolated in 1803 by Berzelius was actually a mixture of cerium, lanthanum and so-called didymium.
		The didymium isolated by Mosander in 1839 was shown to be two separate elements; praseodymium and neodymium.

		Carl Gustaf Mosander was able to separate gadolinite into three materials, which he named yttria, erbia and terbia - a combination of these names results in Terbium.
		Terbium was discovered by Carl Gustaf Mosander in Sweden in 1843.

		Erbium (for Ytterby, a town in Sweden) was discovered by Carl Gustaf Mosander in 1843.
		Mosander separated "yttria" from the mineral gadolinite into three fractions which he called yttria, erbia, and terbia.
		He named the new element after the town of Ytterby where large concentrations of yttria and erbium are located.

	Er Description
		The element was discovered by Carl Gustaf Mosander (1779-1858), who also discovered lanthanum and terbium.
		He had already found lanthanum in yttria, a mixture of rare earth oxides, and he decided to examine this material further in 1843.
		Mosander separated these from the yttria, and, in the portion that remained, he discovered two new oxides: a yellow oxide he called erbia and a rose-colored oxide he named terbia.

		Lanthanum was discovered in 1839 by Carl Mosander, when he partially decomposed a sample of cerium nitrate by heating and treating the resulting salt with dilute nitric acid.
		He separated neodymium, as well as the element praseodymium, from a material known as didymium by means of spectroscopic analysis; however, it was not isolated in relatively pure form until 1925.
		In 1843 Carl Mosander was able to show that yttria could be divided into the oxides (or earths) of three different elements.

	It's Elemental - The Element Erbium
		In 1843, Carl Gustaf Mosander, a Swedish chemist, was able to separate gadolinite into three materials, which he named yttria, erbia and terbia.
		As might be expected considering the similarities between their names and properties, scientists soon confused erbia and terbia and, by 1877, had reversed their names.
		Erbia, the renamed material that Mosander discovered in 1843, is erbium oxide (Er), one of erbium's compounds.

		It is not know exactly when Lanthanum was discovered on Vland, though it is known to have been used as a getter to remove traces of oxygen in electron tubes and in the fabrication of low-dispersion, high-refraction glasses for lens components by about -10,500 Imperial (~5100 P.I.).
		On Terra the element was discovered as the oxide (lanthana) in -2682 Imperial (1839 A.D.) by Carl Gustaf Mosander, who distinguished it from cerium oxide (ceria).
		Its name is derived from the Terran Greek lanthanein, meaning "to be concealed," indicating that it is difficult to isolate.

		Carl Mosander recognized the element lanthanum in impure cerium nitrate in 1839.
		While studying a compound of cerium, he found a new element which he named lanthanum”; from a Greek word meaning “hidden”, because it had been hidden so effectively in those minerals.
		In 1907, Georges Urbain described a process by which Marignac’s ytterbium (1879) could be separated into the two elements, ytterbium (neoytterbium) and lutetium.

		Terbium was discovered in 1843 by Carl Gustaf Mosander, but its existence was not confirmed for about 30 years.
		It was then discovered independently by Per Teodor Cleve in 1879 when he separated it chemically from erbium and thulium.
		Georges Urbain and Carl Auer von Welsbach showed in 1907-1908 that what Marignac had found was in fact two elements, now known as ytterbium and lutetium.

		Tm-169 has potential use in ceramic magnetic materials called ferrites, which are used in microwave equipment.

	Thulium \| World of Scientific Discovery
		The discovery of thulium coincides with the 1840s, which were a period of great activity in the field of rare earth research.
		Largely through the efforts of Carl Gustaf Mosander, the rare earths ceria and yttria were each proven to be highly complex mixtures.
		Eventually, seventeen new elements were to found in these earths.
