This is not easy to react with oxygen, which refers to its chemical properties, that is, its chemical properties are stable, and it is not easy to have chemical reactions with other substances.
The melting refers to its physical properties. Any solid substance will be melted after the external temperature reaches a certain value, and this temperature is what we call melting points.
The melting point of the gold is 1063 ° C, that is, when it is heated to 1063 ° C, the gold will also melt and turn into liquid. After that, "real gold is not afraid of fire refining" will not be established, and gold can obediently obediently. It is processed into various shapes of items, and all kinds of glorious pure gold jewelry is formed.
The gold often exists in the state of natural gold. Natural gold containing silver and copper impurities is essentially different from the alloys of these metals. Metal is a product that is coagulated after metal melting. Therefore, it has a homogeneous structure. Natural gold is precipitated from the aqueous solution. Natural gold sometimes covers a layer of iron oxide film. In this case, the color of gold may be brown, dark brown, and even yellow. This kind of gold generally has a parcel layer. This package layer is not just an iron oxide, sometimes it may be some fine granules attached to the surface of the golden grain. This packaging layer not only affects the recognition of gold, but also makes it difficult to treat it (mercury hybridization or cyanide).

This melting into liquid is a physical change.
