is Gold  a compound.??

Pure Gold is an element, Au.\n\nHowever, the gold you get from shops are not pure gold, but are alloys with other compound, since pure gold is soft at room temperature.

pure compound is any element that is not made of other elements eg.hydrogen

It's actually the substance that's mixed with the gold that's probably causing it. It's something to to do with alkelines and acids or something. Gold is mixed with all kinds of stuff to make jewellry because in it's pure form it't too soft to do anything with. \n\nSo your probably allergic to the metal that's in it (usually Zinc).

A mole of ANYTHING contains Avogadro's number of particles, which is 6.02x10^23 of them.  So if 1 mol of gold =6.02x10^23, then 3.21 mol of gold will have: 3.21mol x (6.022x10^23 atoms/mol)=...atoms of gold

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.

Gold remains gold no matter what. The problem is with the base metals gold jewelry is mixed with. Pure gold is 24 karats. Most of the jewelry you purchase is 14K or 10K. The higher the karat, the more gold. Example, 14K means that it is 14 parts gold, 10 parts base metal (for hardness and color), for a total of 24 parts. Therefore 10K is only 10 parts gold and 14 parts base metal. The base metal oxidizes and changes color. The more base metal (10K) the more likely it is to discolor, become brittle, or break. Touching silver has no effect. Just use a simple cleaner (ammonia and water) or buy a jewelry cleaner. Keep away from bleach, either when cleaning or in chlorinated water. This can do severe damage to the base metals. And do not clean your gold and silver jewelry in the same cleaner. The adverse effect is on the silver, not the gold. Hope this helps.

I have never heard of the "golds" of science.  Besides yellow gold, white gold, and fool's gold....what other golds are there?

Gold\n\nCheck out the cool interactive periodic table in the links below.

In fact the gold has two main valences 1 and 3 but due to his noble character it doenst react with other atoms so probably the concept of valence is not so clear as in more reactive elements.

Gold is VERY heavy, twice the weight of lead. Those movies where people are throwing around gold bricks is far from reality. A cube of pure gold with 14.5 inch sides weighs 2000 pounds!!

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. All three are involved in the electrolytic refining of gold.

it would be Covalentic ofcourse...\n\nIonic is usually when  Metal is reacting with non metal...\n\nin this case , both are not metals so it would be covalentic

It is just from the way that the elements are fused together to form the compound. It's the same as any other metal.

Ionic compound is usually non-metal reacting with metals.\nThat is positive ion forming a compound with negative ion.\nWe call the compound is ionic if the elements we've used have positive or negative charge.\n\nConvalent compunds have different story because they are sharing the electrons and they don't really have any charge.\n\nI don't know what you mean by exactly what kinds of elements make ionic compounds because almost all of them do! Except all the noble gases far right side of table will not react at all (Where there is argon).\n\nIt is that simple

because it depends on the purity(karat)of the gold solution used  for the plating of any metal object.\n\ngold ions from the gold object and the gold solution will be transferred to the object to be plated\n\nif you want to plate the object to be 16K then you use an 16K soulution with an object that contains 16k purity

Ok, so gold's symbol is Au, and it has an atomic mass of about 196.967. Therefore, there are 196.967 grams of Au for each mole of Au.\n\n2.15 mol Au(196.967g Au / 1 mol Au)= 423.47905 grams of Au\n   (2.15 moles of gold is 423.47905 grams)\n\n2.15 mol Au(6.023*10^23atoms Au / 1 mol Au)=1.2943*10^24atom\n    (You multiply the number of moles by Avagadro's number to get the number of atoms present for the number of moles)\n\nTo sum it up:\n   2.15 moles of Au is also:  423.47905 grams of gold \n                                    and\n                              1.2943*10^24atoms of gold \n\nhope that helps

The fact that they are both liquid at room temperature doesn't have any effect on whether they are metalic or not.  Mercury has metallic properties, Bromine doesn't.  Therefore Mercury is metal and Bromine isn't.
