Gold is a noble metal. Gold will not oxidize at any normal enviromental condition.
Gold oxides are unstable compounds and are usually formed by indirect methods. Gold(I) oxide, Au2O, is a covalent compound and is formed by heating AuOH to 200oC. Gold(I) oxide easily reduces to the gold metal. Gold (I) hydroxide, AuOH, is prepared from a Au(I) solution by the addition of potassium hydroxide solution. AuOH dissolves in excess alkali to form aurates, i.e. KAu(OH)2. Gold(III) oxide, Au2O3, is formed by heating Au(OH)3 at 100oC in the presence of a dehydrating agent. Au2O3 also is easily reduced to the metal and dissolves in excess of alkali hydroxide, forming an aurate with the ion [Au(OH)4]-. Gold(III) hydroxide, Au(OH)3, is precipitated by the addition of potassium hydroxide solution in equivalent amount, to a solution of chloroauric acid. Au(OH)3 is insoluble in water, gives many of the reactions of Au2O3, and may be a hydrous form of that compound. Gold(II) oxide is believed to consist of gold(I) and gold(III)
Yes I know it might be complicated, but to answer your question not it will not rust or oxidize under normal conditions.

Gold doesn not tarnish. It's monumentally un-reactive. This is why it has been so prized by people for millenia. Because it doesn't rust or react with anything else to change its appearance it was thought to have some kind of mystical property.

No gold will not rust.
"metal expose to air will rust. wat abt gold" is a wrong proposition. Iron rusts.
