Gold and Silver (and other Noble Metals like Iridium and Palladium) do actually corrode in air, just very very VERY slowly. Bonding with Oxygen is the usual source of chemical corrosion here on Earth, and every metal has its own personal "preference" for bonding with more of itself vs with Oxygen. Iron, for instance, likes Oxygen a lot, and turns into rust without much effort at all. Gold much prefers more Gold to Oxygen, so for the most part, it doesn't corrode. Metals which have very stable structures in a galvanic (electrochemical) sense don't tend to bond to Oxygen very often. Gold and Silver are two of these metals.

Why is platinum found as a metal not an ore?
like gold it does not corrode easily.
Why do gold and platinum do not corrode in moist air?
They are both noble metals, very non-reactive, hence resistant to corrosion.
Do acids corrode metals?
Yes. Some can only corrode soft things, and some can corrode everything. But in short, all acids can corrode something. It only gets dangerous if the acid can corrode you.
Does Platinum go rusty in water?
Platinum does not rust or corrode in any way.
Which property shows that gold does not react with oxygen in the air?

What metal corrodes the slowest in salt water?
The noble metals such as gold, silver, or platinum (etc.) do not readily corrode in salt water
Does alloy gold corrode?
Gold alloys doesn't corrode in normal conditions.
Does gold corrode more easily thans silver?
As i rememeber gold do not corrode at all.
