How would toy test a piece of palladium to see whether it is a metal?

See if it is attracted to a magnet?

yeah, if I could scratch it with a steel knife.  Pyrite would be flaky and would feel like glass almost. Gold would be soft and I could sink a knife into it a bit.  I don't know what silver feels like but I could tell it after I found the first two.

The company I work for does Salt Spray Analysis. it's used to find out how well a coating holds up under controlled conditions. Salt water is very corrosive to most metals and is a good medium for testing for corrosion.\n\nBasically, a part that has a coating (paint, Anodize, Nitride, Black Oxide,...) is placed in a sealed tank. The tank sprays water with a particuar amount of salt in it into the chamber. The parts are checked every hour, 2 hours, 6 hours...as directed by the requirements. As soon as ANY rust is found, the testing stops and the amount of time it took for the rust to show is recorded. 300 hours is very good for any type of paint.

Mag inspection utilizes the phenomenon of ' magnetic lines of force' to indicate flaws in metal castings or machinings.\n\nThis only works with pieces made of ' magnetic' material, such as Iron, steel. ( Stainless and aluminum will NOT work ). \n\nA fine powder of Iron Oxide is sprinkled liberally on the piece to be inspected.  A strong magnetic field is applied from a coil.  If a crack or void exists, the uniform lines of magnetic force will be ' distorted' around the flaw, making the Iron Oxide gather in that area.  The area can then be marked with a grease pen, and analyzed for quality control, rejected, or repaired.

You should take it to a jewlers they will be able to test it for you.

You could determine the copper content of brass (an alloy of copper and zinc) in one of three general ways:\ngravimetric,\nvolumetric,\ncolorimetric.\n\nYou first need to dissolve a known mass of brass completely in nitric acid, neutralise, then transfer to a volumetric flask and make up to volume. \n\nIf you then choose to do it gravimetrically, you should then prepare a stable copper compound of high molecular mass OR you could electroplate out the copper and mass it OR you could simply add excess zinc metal, dissolve any left over zinc with say hydrochloric acid or sulfuric acid, dry and mass the copper. \n\nThere are a number of ways that you could titrate the copper: you could add excess potassium iodide which reacts quantitatively with copper to produce copper(I) iodide and iodine. The resulting iodine can then be titrated with standardised thiosulfate using starch as an indicator. You could also do a complexiometric titration with EDTA.\n\nIf you decide on a colorimetric method, you need to make a standard solution of copper (or brass of known copper content - better) and compare the absorbance of your brass solution with the standard. \n\nYou could do two different determinations and compare results.\n\nThere are many other possibilities, but i do not know what a board project is, or your level of expertise and what equipment you have available. If you need more detail, please re-post and i or someone will be able to help you further.

Put a metal which has higher activity than Silver

You really can't unless the metal in question in tested in an actual circuit. \n\nMany metals (nichrome, for instance) increase greatly in resistance as the current heats them up - and, conversely, some decrease in resistance when heated (many semiconductors, for instance).\n\nThe equation for watts is P=IE, where P is the power or watts, I is the current or amps, and E is the applied voltage. \nOhms Law (R=E/I) will determine the actual resistance of the metal once the above quantities are known.

It's metal and it's an Actinides.

The best test is a streak test. If you are not familiar with this, it is when you rub the mineral across a piece of unglazed porcelain plate or tile.\n\nIn a streak test the gold will leave behind a gold streak while pyrite will leave behind a black one. This works, trust me, I know. All you need is a piece of unglazed porcelain.\n\nYou said earlier about rubbing it across the skin. I have never seen this work however some cheap jewlery is made of pyrite & will leave the fingers, etc. black looking. That is after you wear it a while.\n\nGold is very dense for its size. Pyrite is not nearly as dense. You could do a density test by displacement in water but I assume from what you told me that the "gold" is in a matrix.\n\nPyrite is usually found as a mass of cubic crystals. Sometimes they take on the appearance of a nugget b/c the cubes are very tiny. Gold will not have these cubes.\n\nGold is sometimes found in quartz veins. If you have a chunk of quartz it is possible that there is some gold in there.\n\nGo with the streak test & let us know what happens.\n\n:)

I'm not exactly sure what your talking about, but if you go to unitednuclear.com I'm sure they will have the magnesium you're looking for, unless your talking about an actual test tube made out of magnesium which I've never heard of.

Its probably plastic suregy

Type of plastic that can be used.\nSize of the removal pieces.\nLevel of lead in the paint of toys.\nLabeling for appropriate age.

Guess a group 3 metal such as boron or Aluminium

Looks like it may be E) if it's something you can put under STM and use tunneling effect to make some measurements.

Use a magnet. Iron is attracted to it, lead is not.

rub it with a coin,\nif its gold, a soft metal,\nit should make an indent.\n\nif it is flaky, its fools gold.\n\nand here's a real simple test,\nif they are selling them dirt cheap, they are prob fake.\n\ntoo, what are the chances that a man walked into a mine, picked up some gold ( I am sure that a gold mine is guarded) \nand then managed to get it out of the country, \nand after all that, wants to sell it to you?
