Gold is very inert. And, if you look at the electron state, I believe the gold electrons are not being shared with other elements in the alloy. Thus it would be considered a "mixture".
It is not either. It is a homogeneous mixture.
mixture
surely this is contain copper
This is an alloy, a mixture.
According to a Jewlery Co, yes it does mean 18k. They also use a # designation for 14k. I don't know what it is however. These numbered designations are mainly used in France, England and other European countries. They continue as follows: 22 carat ~ 916 18 carat ~ 750 14 carat ~ 585 9 carat ~ 375 Please note: The English, most especially, utilize "carat" in metal purity. Whereas, in the USA we use the word "karat" for metal purity and "carat" in terms of gemstone weight.
Karat measurements are used for gold, and are not related to diamonds. Karat purity indicates the parts of 24 -- pure gold is 24 karat -- that are gold. Nine, 10, 14 and 18 are common karat purity measurements. Diamonds and pearls are weighed using carats -- one gram equals five carats. Every carat is pure diamond.
It is the carbon group, named after a characteristics element of the group.

The difference between the different types of gold is in the purity of the gold. The karat weight of gold is measured by a gold's purity, with 24 karat gold being pure gold. Therefore, 22 karat gold would have a purity of 22/24 or 91.7 percent, 18 karat gold would have a purity of 18/24 or 75 percent, 14 karat gold would have a purity of 14/24 or 50 percent and 10 karat gold would have a purity of 10/24 or 41.6 percent. As the purity of gold decreases, the alloy in the jewelry increases. Copper and silver are the most common alloys used when making gold jewelry and white gold is usually made with a nickel alloy. The higher karat weight a gold piece of jewelry has, the more valuable that piece of jewelry will be.
This is an alloy and a homogeneous mixture.
It is a homogeneous mixture.. NOT a pure element because of the carat gold
It is a homogeneous mixture.. NOT a pure element because of the carat gold
18 carat is better than 14 carat. 24 carat is pure gold. 18 out of 24 is 75% gold the rest is made up of silver.
A 14 carat gold necklace costs on average $1,230.
583 gold when tested with 14 carat acid changed to green why is that
This is the deal on gold: 12 carat = 50% 14 carat = 58.33% 18 carat = 75% 22 carat = 91.67% 23 carat = 95.83 ...
Gold items are made with the element gold. It can be pure gold or one of a number of metal mixtures called alloys. 14 carat gold is 7/12 gold by weight and 5/12 other metals. 18 carat gold is 3/4 gold. 24 carat gold is pure gold (or very nearly pure, more than 99.5%).
58.5% gold or 14 carat
14 carat gold
The numbers are probably an indication of the purity of the gold. Pure gold is 24 carat but 22 carat, 18 carat, 14 carat and 9 carat are all common.
it is 14 parts gold, 10 parts copper it is givien as a ratio adding up to 24 hence why 24-carat gold is pure gold and you can't get more than that
