Hint: Corrosion is the mechanism by which refined metals are transformed into more solid compounds like metal oxides, metal sulphides, and metal hydroxides. The deposition of iron oxides occurs as a result of the action of atmospheric moisture and oxygen on iron.
Complete answer:
Gold and Platinum are the metals which do not corrode easily. Since they are unaffected by oxygen and other acids, they do not corrode visibly and are more stable than many of their compounds, such as oxides and sulphides. They were given the name noble metals because of their lack of chemical reactivity.
They are pure metal that does not rust due to the absence of iron. Gold is the least reactive of all metals, making it safe to use in both natural and industrial settings. Since gold does not react with oxygen, it can never rust or tarnish.
Corrosion of iron is a major issue because corrosion is both a dangerous and costly problem. Towers and flyovers may collapse, water and oil lines may burst, and chemical industry spills may occur as a result of this crisis. Corrosion happens when all of the atoms on the same ore surface degrade, causing the entire metal surface to be affected.
Note:
Since the metals used in jewellery are often selected on the basis of their reactivity, platinum and gold are used to make jewellery. They are exceptionally lustrous metals that are corrosion resistant. They can be moulded into any shape or pattern because they are extremely malleable and ductile. Hence, they are more expensive compared to other metals.
