My Story The word tungsten means "heavy stone" in Swedish. The chemical symbol for tungsten is W which stands for wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin "like a wolf". Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783. Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength.	My Jobs tungsten is available in many forms including foil, powder, rod, nanosized activated powder, sheet, mesh, and wire. Fun with other metals!

My Nucleus Zinc has thirty protons and an average of thirty-five neutrons; its average atomic mass is 65.38. Zinc occurs in nature in four stable isotopes: zinc-64, zinc-66, zinc-67, and zinc-68. Zinc-64 is the most abundant of those four. Zinc has twenty-two radioactive isotopes. Two common ones are zinc-65, which has a half-life of 244.26 days, and zinc-72, which has a half-life of 46.5 hours. All other isotopes have half-lives ranging from less than one second to fourteen hours.	My Electrons Neutral zinc atoms have thirty electrons, including its two valence electrons.

Zinc yellow is used as a pigment. Sodium zincate is a water softener. Homer Simpson's head x-ray brass reacts with chlorine to make zinc chloride
My Story Zinc has been used since 1100 B.C. in brass and other alloys. Romans were making brass by 30 B.C. with calamine (which contains zinc oxide) and copper. In 1000 A.D. in China and India, zinc's pure form could be extracted. Andreas Margraff is credited with the discovery of zinc in 1746. In 1744, zinc had already been isolated by another chemist named Anton von Swab, but Margraff's reports were much more detailed, and his research was more accurate so Margraff got credit. The name "zinc" could come from a scientist named Agricola. He observed that this metal was found in furnaces that metled zinc ore, and called it "zincum". zinc ore	My Jobs Zinc is used to galvanize iron and make alloys such as brass, German silver, Babbitt metal, and bronze. Zinc is used in making negative plates in some electric batteries, and roofing and gutters. Zinc helps growth in many plants and animals. It is also used to treat diabetes, because it is in insulin. Zinc also makes up 98% of the US penny. zinc gutters

(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 Compounds

In compounds of ytterbium , most commom oxidation numbers of ytterbium are 3

(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)

My Story
Lanthanum was discovered in 1839 by Swedish chemist Carl Gustav Mosander, when he partially decomposed a sample of cerium nitrate by heating and treating the resulting salt with dilute nitric acid. From the resulting solution, he isolated a new rare earth he called lantana. Lanthanum was isolated in relatively pure form in 1923. The word lanthanum comes from the

Greek λανθανω [lanthanō] = to lie hidden.

My Jobs
Lanthanum has no known biological role. The element is not absorbed orally, and when injected its elimination is very slow. Lanthanum carbonate was approved as a medication to absorb excess phosphate in cases of end-stage renal failure. Some rare-earth chlorides, such as lanthanum chloride (LaCl3), are known to have anticoagulant properties.

Carbon lighting applications, especially by the motion picture industry for studio lighting and projection.
La2O3 improves the alkali resistance of glass, and is used in making special optical glasses, such as:
- Infrared absorbing glass.
- Camera and telescope lenses, because of the high refractive index and low dispersion of rare-earth glasses.
Small amounts of lanthanum added to steel improves its malleability, resistance to impact and ductility.
Small amounts of lanthanum added to iron helps to produce nodular cast iron.
Small amounts of lanthanum added to molybdenum decreases the hardness of this metal and its sensitivity to temperature variations.
Mischmetal, a pyrophoric alloy used e.g. in lighter flints, contains 25% to 45% lanthanum.
Lanthanum oxide and the boride are used in electronic vacuum tubes as hot cathode materials with strong emissivity of electrons. Crystals of LaB6 are used in high brightness, extended life, thermionic electron emission sources for scanning electron microscopes.
in Gas tungsten arc welding electrodes, as a substitute for radioactive thorium.
Hydrogen sponge alloys can contain lanthanum. These alloys are capable of storing up to 400 times their own volume of hydrogen gas in a reversible adsorption process.

earliest uses were to use with bronze.

My Jobs

used to coat other metals to prevent corrosion or other chemical action (tin cans are made from tin coated steel)
alloying agent, important alloys incldue soft solder, type metal, fusible metal, pewter, bronze, bell metal, Babbitt metal, White metal, die casting alloy, and phosphor bronze
the chloride (SnCl2.H2O) is used as a reducing agent and as a mordant in calico printing
tin salts sprayed onto glass are used to produce electrically conductive coatings. These have been used for panel lighting and for frost-free wind-shields
window glass is made by floating molten glass on molten tin (float glass) to produce a flat surface (Pilkington process)
a crystalline tin-niobium alloy is superconductive at very low temperatures. Such magnets, made of tin-niobium wire, weigh just a few pounds and produce magnetic fields that are comparable to that of a 100 ton electromagnet
trialkyl and triaryl tin compounds are biocides - there is concern over their environmental effects. Tributyltin is the active ingredient in a type of antifouling paint used on ships.
