Want this question answered?
they have low reactivity
Samples of platinum and copper can have the same extensive properties but not the same intensive properties for a couple of reasons. These are both metals but have differing numbers of electrons.
Really none. That is why gold is so valuable. While other metals have similar properties to gold, none of them have the exact same. The closest metals to gold in terms of its properties are silver, platinum and palladium.
B'coz they are less reactive than other metals..
The most important property of the metals that are suitable for jewellery is that they do not oxidize easily. These metals are at the bottom of the activity series, and they are copper, silver, mercury, platinum, gold.
they have low reactivity
Many different metals are used. Jewelry is often based on certain expensive metals such as gold, platinum, or silver, but other metals are used as well.
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.

Platinum jewelry is marked "Plat" or "950 Plat" and is nearly pure platinum. "IridPlat" is 90 percent platinum mixed with 10 percent other metals.

The answer to this question is gold. Gold is one of most expensive metals in the world. This answer was answered by tom hills of falmouth... waii
Metals do not react with substances in our skin. Also, they are malleable, which allows for us to shape them to make jewelry.
Platinum silver and gold are the main ones. Sometimes traces of copper are used for alloying the gold.
There are multiple types of gold aside from the traditional yellow gold. White gold and rose gold are commonly used in jewelry making. Other precious metals commonly found in jewelry are silver and platinum. Silver is a soft metal and is typically mixed with other metals such as copper. Platinum is much more rare than gold or silver and tends to be far more expensive.
