Gold does not react with oxygen because of its atomic structure which makes it very stable. As it is entirely stable, there is no need for it to react with oxygen to gain stability. Conduction of heat has nothing at all to do with it. Iron is an excellent conductor of heat but reacts readily with oxygen.

Gold does not corrode/tarnish.
Gold does not react directly with oxygen, however if you succeed in getting gold oxide indirectly, it decomposes at 205C. The oxide is neither acid nor base however gold ions are acidic (like protons are acidic)

Yes, gold can react with oxygen to form gold oxide.
Does gold rust. Gold can not rust. Rust is oxidation, and gold is inert to oxygen and even most acids. Why doesn't goldrust. Because it's a special metal iron.
Gold is said to be noble metal because it is unreactive and does not react with either oxygen or water.
because gold is a metal it conducts heat and electricity very well

Because it does not react (noble). Most other metals will be found in compounds based on their oxides, however if gold would react with oxygen, which it does not directly, then under heat or light it will decompose back to gold

the ability to not react with oxygen in the air.
Gold reacts with few elements including chlorine, oxygen and fluorine under critical conditions.
gold will not react with lead nitrate because gold is the least reactive metal- it hardly reacts with anything
