Silver and gold do not react with oxygen even at high temperatures due to their high resistance to oxidation. Both metals have a noble or inert character, meaning they have a stable configuration of electrons that doesn’t readily lend itself to forming compounds with oxygen. This inherent stability of their electron configuration makes silver and gold highly unreactive, preventing the formation of oxides even when exposed to elevated temperatures. Their resistance to corrosion and oxidation contributes to the luster and durability that make silver and gold highly valued for jewelry and various applications where stability is crucial.
