I don't know what are the uses of metalloids. Could you please reply me?

Together with the metals and nonmetals, the metalloids (in Greek metallon = metal and eidos = sort - also called semimetals) form one of the three categories of chemical elements as classified by ionization and bonding properties. They have properties intermediate between those of metals and nonmetals. There is no unique way of distinguishing a metalloid from a true metal but the most common is that metalloids are usually semiconductors rather than conductors.\n\nThe known metalloids (and their atomic symbols) are:\n\nBoron (B) \nSilicon (Si) \nGermanium (Ge) \nArsenic (As) \nAntimony (Sb) \nTellurium (Te) \nPolonium (Po) \nAstatine (At) \nIn the periodic table, metalloids occur along the diagonal line from boron to polonium. Elements to the upper right of this line are nonmetals; elements to the lower left are metals.\n\nSemi-metallic behaviour is not confined to the elements, but is also found in alloys and compounds. Mercury (II) telluride is one example.\n\nOne definition of semi-metallic behavior would be if the conduction band and valence band overlap. This is also true of metals, so semi-metals must additionally have a relatively low carrier density.

U r asking for a science project.?\nI have an idea for the science project for chemistry side

I'm not the best at chemistry, in fact, I was crap at it.. but I'll give it a go...\n\nA) Can A\n\nB) The Zinc will react to the juice, giving it a bad taste and make it dodgy.\n\nC) Copper is good for containing liquids, this is why the water supply system and pipes are made of Copper... instead of Lead, of course!\n\nD) Probably not, Zinc doesn't go down too well with juice (I think) and it may have reacted badly.\n\nIs that any good? What I know about chemistry can be written on the back of a postage stamp!

In an electrolytic cell you can plate most any metal that doesn't quickly react with the solvent and its solutes.  The force of the copper ions gaining electrons at a negative charged zinc electrode is certainly possible.\n\nSince the copper would receive two electrons and go from a +2 to a zero oxidation state, you would say that it is being reduced.

Because there will always be interactions between all the elements in a compund except for a bridging ligand, we can asusme that we need to take into account the charge on each atom. \n\na element in group 2 is always +2\na element in group 4 is +2,3,4\nOxygen is is -2\n\nknowing we have a neutral charge we can immedialty eliminate C and as we know that we must use all of our atoms the only answer that makes sense is D

Actually the copper doesn't come directly from the solution...\n\nNot sure how much detail you want, but it does use electroplating.  This means that it uses electricity to plate metal on an object.  The stainless steel object is put on the "positive end" and a lump of pure copper is placed on the "negative end."  A low voltage is used because a high voltage plates too fast, and the layer will peel off quickly.  If copper is the plating, then the solution must be a fairly low-concentration copper sulfate (CuSO4) solution, meaning that copper is the only metal present in the electrochemical cell.  The negative end is called the anode, and this decreases in mass as its copper ions are taken to the positive end -- the cathode.  \n\nThis method of plating multiple metals is actually fairly common, because the properties of each one can be combined.  Nickel can be used for farm equipment and engines because it can withstand a lot of force, silver is used for decoration, chromium is used to withstand a lot of use (like a spoon).  Copper is able to conduct heat and helps food cook evenly.

There are thousands of polymers all with very different chemical and physical properties.  so a simple answer can not be given.  perhaps a specific polymer would obtain better responses.

It is not due to the chemistry of copper or gold.\n\nIt is due to the electronic band structure. The two metals unusually have a band structure that causes them to absorb light at certain frequencies rather than reflecting it.

Its a salt of beryllium and is toxic and is mainly used to extract the beyllium from it and hence is an mineral. Beryllium is used in aerospace and defense industry as light weight structural material. Beryllium is used in nuclear weapons for similar reasons. \n\n\nBeryllium is used as an alloying agent in the production of beryllium-copper because of its ability to absorb large amounts of heat. Beryllium-copper alloys are used in a wide variety of applications because of their electrical and thermal conductivity, high strength and hardness, nonmagnetic properties, along with good corrosion and fatigue resistance. These applications include the making of spot-welding electrodes, springs, non-sparking tools and electrical contacts.\n\n\nThin sheets of beryllium foil are used with X-ray detection diagnostics to filter out visible light and allow only X-rays to be detected.\n\n\nBecause it has a low thermal neutron absorption cross section, the nuclear power industry uses this metal in nuclear reactors as a neutron reflector and moderator

Beryllium is a moderator...it is used to slow down neutrons

The latest technology is bio extraction using plants and microbes to extract gold from the source rocks.\n\nI suggest that you go in for cyanide method. Not free cyanides but in the complexed form.

Some quick help now\n1. Brass is a solid solution; copper is the solvent and zinc is the solute it is also an alloy so it may get you 6 as well. \n2. A bottle or can of a soft drink unopened is LeChatelier's Principle. It is at stasis until it is opened, thus the volume is larger and the equilibrium is disturbed until it gets back to equilibrium by outgassing the CO2.\n3. Take salt and sugar and mix them together. Large state of entropy. Hard to unmix them. \n5. Volatile solid: mothballs - naptha. Viscuous liquid - container of car engine oil\n7. That is a mole of something. Water H2O - 2 Hydrogens + 1 oxygen  (2 X 1.00 + 1X 15.999 = 18 atomic mass units) = 18 amus expressed as grams = 18 grams has 1 mole 18 grams of water is 18 ccs. So get something that holds 18 ccs or 18 mls of water. Small bottle.

Well, you'd have to specify what you are trying to dissolve.  Many plastics are soluble in several solvents... N-Methylpyrrolidone being a good one.  Solvents generally do not attack metals, unless they contain water.  I would steer away from an acid or a base.  Can you say what you're thinking of?  If so, email me at connecticutpoet37@yahoo.com

Oxygen - Water, that should be easy to talk about.\n\n"Among the relatively few gold compounds of practical importance are gold(I) chloride, AuCl; gold(III) chloride, or gold trichloride, AuCl3; and chlorauric acid, HAuCl4.

analize an existing polymer with as many properties of the ones you are looking for, determine the formula ( possibly use a mass spectrometer for the recipe,)  experiment with the atomic structure of the elements in the formula. wouldn't it be great if you could manipulate the structure at subatomic level, i.e. at levels below protons and neutrons like quarks.\ntry changing the formula ( recipe?) at its basic level, with different proportions of at least carbon and hydrogen, possibly adding 'alloying' elements into the atomic structure.
