Artifical radioactivity
A copper sheet is made of... surprise... copper. No gold.
Copper and gold; copper is brown when in a pure state (green is more familiar, but that's actually an oxidized copper), and gold is yellow.
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
Nitric acid can dissolve copper but not gold. Gold is resistant to most acids, including nitric acid, which is commonly used to dissolve copper.
To mix copper alloy for 1 gram of 24k gold to create 21k gold, you need to reduce the gold content from 24k (100% gold) to 21k (87.5% gold). This means you will require 0.875 grams of pure gold and 0.125 grams of copper alloy (which typically contains copper and possibly other metals). To achieve this, mix approximately 0.125 grams of copper with your 0.875 grams of 24k gold.
Copper cannot be converted into gold through any scientific process or alchemical transformation. The idea of turning base metals into gold is a concept from medieval alchemy that has no basis in reality.
r u fool . gold is hardend metal and copper is soft .
Some metals that are not silver gray in color include gold (yellow), copper (orange-red), brass (yellow-brown), and bronze (reddish-brown).

No, gold will not replace copper from a copper sulfate solution through a displacement reaction. Gold is less reactive than copper and cannot displace it in a chemical reaction.
Copper and gold; copper is brown when in a pure state (green is more familiar, but that's actually an oxidized copper), and gold is yellow.
Artificial gold can refer to either synthetic gold (such as gold produced in a lab) or gold-plated materials. In both cases, the gold itself is a pure substance as it consists solely of gold atoms. However, if it is an alloy or combined with other metals, then it would not be considered a pure substance.
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
Copper into gold, means putting copper powder in gold salt solution. Because copper is closer to hydrogen then gold, in the electromotive scale, it will dissolve, freeing the gold
Copper is much more common than gold.
There is no copper in gold unless it has been intentionally added in an alloy. If you are referring to an alloy such as rose gold, the amount of copper would depend on the specific composition of the alloy.
Gold is softer than copper. Copper is stronger and has a higher tensile strength compared to gold. This is why copper is often used for electrical wiring and plumbing where strength is important.
