Hint: Metals that do not easily react with other elements are called noble metals. These metals do not corrode and are not easily attacked by acids. Noble metals have outstanding resistance to oxidation, even at high temperatures.
Complete answer:
Examples of noble metals are gold, platinum, silver etc.
Noble metals are the metals of group \[VIIb\], \[VIII\], and \[Ib\] of the second and third transition series of the periodic table.
The noble metals are iron-lovers. They tend to sink into the Earth's core because they dissolve readily in iron either as solid solutions or in the molten state. Most of these elements have practically no affinity whatsoever for oxygen. Copper, silver, gold, and the six platinum group metals are the only noble metals that occur naturally in relatively large amounts.
In physics, the noble metal expression is sometimes confined to copper, silver and gold, since their full d-subshells contribute to what noble character they have. In contrast, the other noble metals, especially the platinum group metals, have notable catalytic applications, arising from their partially filled d-subshells.
Note:
Silver and gold, which with copper are often called the coinage metals, and platinum, iridium, and palladium comprise the so-called precious metals, which are used in jewellery.
Jewelleries and other items made from gold are cleaned through aqua regia. It is a mixture of thionyl chloride and the organic solvent pyridine. It is also tuneable to a specific metal.
