  My Home (Body,planet, universe) Ytterbium is a natural metal that can be found on earth. Ytterbium metal is available commercially so it is not normally necessary to make it in the laboratory, which is just as well as it is to isolate as the pure metal. This is largely because of the way it is found in nature. The lanthanoids are found in nature in a number of minerals. The most important are xenotime, monazite, and bastnaesite. The first two are orthophosphate minerals LnPO4 (Ln deonotes a mixture of all the lanthanoids except promethium which is vanishingly rare) and the third is a fluoride carbonate LnCO3F. Lanthanoids with even atomic numbers are more common. The most comon lanthanoids in these minerals are, in order, cerium, lanthanum, neodymium, and praseodymium. Monazite also contains thorium and ytrrium which makes handling difficult since thorium and its decomposition products are radioactive.	YttErBiUm Ytterbium has a bright silvery lustre, is soft, malleable, and quite ductile. While the element is fairly stable, it should be kept in closed containers to protect it from air and moisture. Ytterbium is readily attacked and dissolved by mineral acids and reacts slowly with water.

  (My Story) Discovered By : Jean de Marignac Discovered at : Switzerland Discovered in : 1878 Origin of name : Named after the village of "Ytterby" near vaxholm in Sweden In 1878 Marignac discovered a component, which he called ytterbia, in the earth then known as erbia. In 1907, Urbain separated ytterbia into two components, which he called neoytterbia and lutecia. The elements in these earths are now known as ytterbium and lutetium, respectively. These elements are identical with aldebaranium and cassiopeium, discovered independently and at about the same time by von Welsbach. The impure element was first prepared by Klemm and Bonner in 1937 who reduced ytterbium trichloride with potassium. Daane, Dennison, and Spedding prepared a purer form in 1953 from which the chemical and physical properties of the element could be determined.

Chemical reactions of the elements

Reaction of ytterbium with air

Ytterbium metal tarnishes slowly in air and burns readily to form ytterbium (III) oxide, Yb2O3.
4Yb + 3O2 → 2Yb2O3

Reaction of ytterbium with water

The silvery white metal ytterbium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form ytterbium hydroxide, Yb(OH)3, and hydrogen gas (H2).
2Yb(s) + 6H2O(g) → 2Yb(OH)3(aq) + 3H2(g)

Reaction of ytterbium with the halogens

Ytterbium metal reacts with all the halogens to form ytterbium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively ytterbium(III) bromide, YbF3, ytterbium(III) chloride, YbCl3, ytterbium(III) bromide, YbBr3, and ytterbium(III) iodide, YbI3.
2Yb(s) + 3F2(g) → 2YbF3(s) [white]
2Yb(s) + 3Cl2(g) → 2YbCl3(s) [white]
2Yb(s) + 3Br2(g) → 2YbBr3(s) [white]
2Yb(s) + 3I2(g) → 2YbI3(s) [white]

Reaction of ytterbium with acids

Ytterbium metal dissolves readily in dilute sulphuric acid to form solutions containing the colourless aquated Yb(III) ion together with hydrogen gas, H2. It is quite likely that Yb3+(aq) exists as largely the complex ion [Yb(OH2)9]3+
2Yb(s) + 3H2SO4(aq) → 2Yb3+(aq) + 3SO42-(aq) + 3H2(g)

Reaction of ytterbium with bases
