Does anyone know what the texture of the Element Ruthenium is?

Name: ruthenium\nSymbol: Ru\nAtomic number: 44\nAtomic weight: 101.07 (2) g\nCAS Registry ID: 7440-18-8\nGroup number: 8\nGroup name: Precious metal or Platinum group metal\nPeriod number: 5 \nBlock: d-block\nDescription \n\nHere is a brief description of ruthenium.\nStandard state: solid at 298 K\nColour: silvery white metallic\nClassification: Metallic\nAvailability: \n\nRuthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM).\n\nRuthenium is a hard, white metal. It does not tarnish at room temperatures, but oxidises in air at about 800°C. The metal is not attacked by hot or cold acids or aqua regia, but when potassium chlorate is added to the solution, it oxidises explosively. \nIsolation\nHere is a brief summary of the isolation of ruthenium. \n\nIt would not normally be necessary to make a sample of ruthenium in the laboratory as the metal is available, at a price, commercially. The industrial extraction of ruthenium is complex as the metal occurs in ores mixed with other metals such as rhodium, palladium, silver, platinum, and gold. Sometimes extraction of the precious metals such as iridium, rhodium, platinum and palladium is the main focus of a partiular industrial operation while in other cases it is a byproduct. The extraction is complex because of the other metals present and only worthwhile since ruthenium is useful as a specialist metal and is the basis of some catalysts in industry.\n\nPreliminary treatment of the ore or base metal byproduct is required to remove silver, gold, palladium, and platinum. The residue is melted with sodium bisulphate (NaHSO4) and the resulting mixture extracted with water to give a solution containing rhodium sulphate, Rh2(SO4)3. The insoluble residue contains the ruthenium. The residue is melted with Na2O2 and extracted into water to extract the ruthenium and osmium salts (including [RuO4]2- and [OsO4(OH)2]2-). The residue contains iridium oxide, IrO2. Reaction of the salt with chlorine gas gives the volatile oxides RuO4 and OsO4. The ruthenium oxide is dissolved by treatment with hydrochloric acid to form H3RuCl6, and the ruthenium precipiated out as pure (NH4)3RuCl6 by treatment with NH4Cl. Evaporation to dryness and burning under hydrogen gas gives pure ruthenium.

Need to know the type of metal and thickness to answer this question.

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

go to www.google.com them write periodic table and than go to images and you'll see

Of those three are elements: Gold, Platinum, and Aluminium\n\nOne of them is a molecular compound: Sugar (each sugar molecule is the same, but is composed of many elements)\n\nOne of them is an alloy: Brass (composed of a melt of several metalic elements)\n\nReally depends of what your definition of "pure substance" is.

You should try the "Physics Handbook", the "Handbook of Thin Film Technology"\n\nThe Handbook of Physicochemical Properties of the Elements (but this one may be available only in russian).\n\nYou may also try this article in an university library:\n\nL. Vitos, A. V. Ruban, H. L. Skriver, and J. Kollar, The surface energy of metals, Surf. Sci. 411, 186 (1998).

You are right! Atomic structure has everything to do with what wavelengths are absorbed, and which ones are reflected. I works with light, and it works with radio waves... Thats how they make stealth aircraft. Funny thing about copper... when powdered and burned, it makes a pretty green color!

Gold and silver are not ferromagnetic materials and so do not have any magnetic properties. \n\nThe following explanation is from school for science.com  \n\n"Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), cobalt (Co) and gadolinium (Gd) are such materials. \n\nThe reasons these metals are strongly attracted are because their individual atoms have a slightly higher degree of magnetism due to their configuration of electrons, their atoms readily line up in the same magnetic direction, and the magnetic domains or groups of atoms line up more readily. \n\nIron and steel\nIron is the most common element associated with being attracted to to a magnet. Steel is also a ferromagnetic material. It is an alloy or combination of iron and several other metals, giving it greater hardness than iron, as well as other specialized properties. Because of its hardness, steel retains magnetism longer than iron.\n\nPermanent magnets\nAlloys of iron, nickel, cobalt, gadolinium and certain ceramic materials can become "permanent" magnets, such that they retain their magnetism for a long time."\n\nTry looking at the website for more information. Hope that helps!

Los Alamos national lab has a good periodic table/ elemental factoids.\n\nLanthanum is La.  It is the beginning of the "Lanthanides".

Some metallic and some non-metallic.\nLike Silicium... it it shiny, just like metals, but doesn't conduct electricity, just like non-metals.\nOr Carbon... it is not shiny and doesn't react with acids, like non-metals, but conduct electricity, like metals.

I'm sure you mean rhodium.\n\nhttp://en.wikipedia.org/wiki/Rhodium

Iridium, a metal of the platinum family, is white, similar to platinum, The specific gravity of iridium is only very slightly lower than osmium, which is generally credited as the heaviest known element. Calculations of the densities of iridium and osmium from the space lattices give values of 22.65 and 22.61 g/cm^3, respectively. These values may be more reliable than actual physical measurements. At present, therefore, we know that either iridium or osmium is the densest known element, but the data do not yet allow selection between the two. Although its principal use is as a hardening agent for platinum, iridium is also used to make crucibles and devices requiring high temperatures. It is also used for electrical contacts. \nThe element forms an alloy with osmium which is used for tipping pens and compass bearings.

If you are looking for properties of some specific chemical then search for MSDS (Material Safety Dada Sheet) for that particular chemical in Google or Yahoo search engines.\nHere, I am giving you a list of websites which can give you general information on symbols. There will be slight variation in the depth of descriptive material depending on site to site.\nYou can copy and paste following links in your browser's address line:\n(1) www.geocities.com/david_charles_curran/safety\n(2) http://en.wikipedia.org/wiki/Hazard_symbol\n(3) http://www.hse.gov.uk/chip/phrases.htm\n(4) http://www.chem.utoronto.ca/healthsafety/guide/symbols.htm

Although I don't understand why you wouldn't just search for the answer, it is ununbium, which is the temporary IUPAC name for an element synthesized for a brief time (<< 1s) in around 2002 and 2004. It is not naturally occuring and little is known about it.
