whitch is heavier lead or gold?

It would depend on how much you have.\nWhich is heavier, a pound of feathers or a pound of rocks?\n-They weigh the same.\n\nLead has a density of about 11.3 grams per cc,\nGold has a density of about 19.3 grams per cc,\nso for a given volume, gold is much heavier than lead.

Gold is naturally a yellow color.  White gold is an alloy of gold and another metal.  Here's what I found online:\n\nWhite gold is an alloy of gold and some white metals such as nickel, silver and palladium. White gold can be 9k, 10k, 12k, 14k, 18k, or any karat up to 24k. For example, 18k yellow gold is made by mixing 75% gold with 25% other metals such as copper and zinc. 18k white gold is made by mixing 75% gold with 25% other metals such as nickel, silver and palladium. So the amount of gold is the same but the alloy is different.

You might be looking for information on alchemy, not chemistry.  The two fields of study are very seperate these days.  Of course, modern scientits could turn lead into gold by nuclear fusion, or turn heavier elements into gold by fission- neither process seems practical.

If you can measure the weight and volume of the ring, you could find its density.  The value will be different depending on what purity it is (24k will be denser than 12k, for example).  Most gold in jewelry is not 24k, but some alloy with nickel, copper, etc. that makes it harder.  These alloys are also how you get white, pink, and green gold.\n\nBiting a ring will only give you marks if it is 24k gold.\n\ndensity would be the easiest way, I'd say.  (density = mass/volume)\nYou'll need the equipment to measure pretty small masses and volumes, though, which most people don't have in their kitchens.

i agree that it's probably lead.  lead is very dense, so your things should feel very heavy for their size.  you can verify this by a couple methods:\n\n1.  get an accurate scale and measure the weight of a piece.  then get a graduated cylinder from your school and fill it partway with water.  dunk the same piece of the metal into the water and see how much the volume changes.  divide the weight by the volume to get the density.  compare this to the density of lead which is 11340 kg/m^3 or 11.34 grams/mL.\n\n2.  if you have a voltmeter, do the following:\n - get a tub of water and dissolve some salt in it\n - cut out a strip of aluminum foil and immerse one end in the water\n - take your mystery metal and immerse one end in the water\n - make sure the two metals aren't touching\n - connect one probe of the voltmeter to the aluminum, and the other probe to the metal.\n - aluminum has an electrode potential of 0.13 V and aluminum has an electrode potential of 1.66 V, so if lead is the metal then the voltmeter should read 1.66 - 0.13 = 1.53 V.\n\nsounds like you are going to have some fun!\n\nalso, lead is toxic so wear gloves and wash your hands after you handle it.

It is a very pure conductive metal. More pure than gold. Indeed.

Gold is an element and it's just called Gold.\nA mixture of gold with other elements may be referred to as a compound containing gold eg, gold nitrate.\nThe quality and hence the value of gold is rated in units called karats.

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 higher the number the more gold, percentage wise\n\nGold is a precious metal that has been valued by people since ancient times. People use gold for coins, jewelry, ornaments, and many industrial purposes. Until recently, gold reserves formed the basis of world monetary systems. \n\nGold is a very soft metal when it is pure (24 Kt. is pure gold). Gold is the most malleable (hammerable) and ductile (able to be made into wire) metal. Gold is usually alloyed (mixed with other metals, often silver and copper) to make it less expensive and harder. The scientific abbreviation of gold is Au. \n\nThe purity of gold jewelry is measured in karats. Some countries hallmark gold with a three-digit number that indicates the parts per thousand of gold. In this system, "750" means 750/1000 gold (equal to 18K); "500" means 500/1000 gold (equal to 12K).\n\nTherefore 14K is better.

The only way to turn metals into gold is to change the number of neutrons and protons (most importantly protons) in the nucleus.  That is THE only way.  Alchemy only leads to dead ends.  Don't be fooled by things that look golden.

By law, gold filled has 1/20th by weight layer of gold permanently bonded over a core of base metal. \n\nGold plate has a few microns coating of gold over the base metal.\n\nGold filled is more expensive, and more enduring.

Think of it this way:  If an object weighs more than it would if it was made of water, it will sink.  If an object weighs less that it would if it was made of water it will float.\n\nA coin is made of solid metal which makes it denser than water, therefore heavier.  It will sink.  A ship is made of metal also, but NOT solid metal.  It also consists of other materials but mainly air (inside the ship).  This means it's lighter than water, which is why it will float.

The same way that Archimedes did -- determine the density.\n\nMeasure the mass of the coin, then determine its volume by water displacement.\n\nDensity = mass/volume\n\nThe density of pure (24 karat) gold is 19.3 grams/cm3\n\nFor other alloys and karat ratings of gold, check this table:\nhttp://www.24carat.co.uk/densityofgoldandothermetalsframe.html\n\nMost U.S. gold coins in current production are 22 karat gold.\n\nYou may need to do some more research to determine the expected gold content of your coin, and then you can compare it to the chart for a density value.

White gold is an alloy of gold that contains another metal, like platinum, causing it to look more like silver.  While gold always contains less actual gold than pure gold, but may be more valuable on an ounce basis if the alloy metal is more valuable than gold.  One common use of white gold is to make the metal much harder than 24 carat gold so that it is more resistant to dents and other damage.

I would assume that lead pellets would be heavier than aluminum. Try placing them in a liquid which is buoyant for aluminum and the lead should fall to the bottom. Thick Veg Oil or something? A magnet might work too. Not sure though.

nope...it is only made of 6 grams of gold...the other 54 grams is brass or other metals
