It's prettier and rarer.
You are wrong. Copper is NOT more expensive than gold.
Copper is the best material for electrical wires due to its high electrical conductivity and low resistance, which allows for efficient transmission of electricity. Silver is slightly more conductive than copper but is much more expensive, while gold, while highly conductive, is even more expensive and less practical for everyday use.
Rose gold is better and could be expensive because it is rare but its only a mixture of yellow gold and copper. but the color could go bad if any perfumes or cremes are accidentally put on it. Yellow gold (pure gold) is more expensive than an alloyed gold.
Copper is used instead of gold because gold is way to expensive and not practical.
Too expensive, it would be stolen (as it is there are people stealing copper electrical wiring, and copper is much cheaper than gold).
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.
We don't see gold wire used in microwave ovens. Gold wire is super expensive, and we can use copper more easily and for less money.
Copper is much more common than gold.
There was a gold rush, not a copper rush, for one. Also, our nation onced had a gold standard, not a copper standard, for gold is much more valuable. In the old days, scientists tried everything that they could think of to turn rocks and such into gold for a reason, and that reason was the fact that gold in any amount, was worth a fortune! Plus, you never hear of 24 karot copper jewelry, do you? Copper is for wiring and such, as gold is too good of a metal for that.
Silver is a metal that is a better conductor than copper. It has a higher electrical conductivity that makes it more efficient for transmitting electricity. However, silver is more expensive than copper, so copper is typically more widely used in electrical applications.
The price difference between white gold and yellow gold typically comes down to the alloys used in each. White gold often contains more expensive metals such as palladium or platinum, making it slightly more costly than yellow gold, which is often alloyed with less expensive metals like copper and zinc. Ultimately, the price difference can vary depending on market prices and any additional factors such as craftsmanship or design.
gold is more expensive than iron simply because iron is more common and gold is also a purer metal
