Want this question answered?
they have low reactivity
They are nonreactive because people where them for jewelry and they dont cause irratation of such sort.
Reactivity of metals is an important characteristics that is used almost in all electrochemical cells.Some metals such as copper, aluminum, iron etc can undergo rapid red-ox reaction in a chemical cell. On the other hand, certain metals such as platinum and gold, also known as inert electrodes have very low reactivity.
B'coz they are less reactive than other metals..
The first few in the reactivity series... copper, lead, platinum and silver.. Gold occurs native.
they have low reactivity
Tantalum, platinum and gold are very stable metals and 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.
Copper, Mercury, Platinum, Silver, Gold. check the reactivity series, it may help.
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
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.
Platinum silver and gold are the main ones. Sometimes traces of copper are used for alloying the gold.
Platinum or Gold.
