Why gold is not react with oxygen?

Question

Answer

Oxygen is mostly unreactive with gold and platinum. When an oxide reacts with water, a metal hydroxide is produced. Oxygen is very reactive with Alkali metals. Alkali metals are given the name alkali because the oxides of these metals react with water to form a metal hydroxide that is basic or alkaline.

Answer

Gold is a noble metal whose reactivity is very less. It reacts with a very few substances. Oxygen is one of those substances it doesn't reacts with.

Answer

Because gold came in low reactivity metal . it reacts with a few substances.

Answer

Because gold is the least reactive metal.

Answer

Gold is a least reactive metal

Answer

Why Gold Does Not React with Oxygen
Gold is a noble metal that does not react with oxygen under normal conditions. This unique property can be attributed to several factors:

Chemical Stability: Gold is a noble metal, which means it is resistant to oxidation and corrosion. Its outer electron configuration is such that it does not readily lose or gain electrons, making it chemically stable.
Lack of Electronegativity: Gold has a low electronegativity, which means it does not easily attract or share electrons with other elements like oxygen. This results in a lack of chemical reactivity with oxygen.
Formation of an Inert Surface Layer: When exposed to oxygen, gold forms a thin layer of gold oxide on its surface. However, this oxide layer is highly stable and acts as a protective barrier, preventing further oxidation of the metal.
Formation of Gold Clusters: Gold nanoparticles can form clusters that exhibit unique electronic properties. These clusters have been shown to be even more stable and inert towards oxygen compared to bulk gold.

Overall, the combination of gold's chemical stability, low electronegativity, formation of a protective oxide layer, and unique electronic properties in the form of clusters all contribute to its non-reactivity with oxygen. This property makes gold highly valuable in various applications, from jewelry and currency to electronics and medical devices.
