Before answering about gold, let's think a little bit about what rusting is. As the name says, rust is something that happens to iron. When iron is exposed to air in the presence of water, it undergoes a transformation, a chemical reaction that produces something that wasn't there before: the rust or iron oxide, that orange material that forms on top of the iron.
If you leave a wet steel wool in the sink, it will quickly turn brown. Rust is a compound that contains oxygen and iron. When we talk about other metals reacting with oxygen and forming oxides, we don't use the term rust, but oxidize.
You may have noticed copper coins that, after a while, turn dark. This is because copper oxidizes. If you put some vinegar or lemon juice on the coin, the acid will dissolve the copper oxide and the coin will look shiny as new. We can put the metals in a row, in order of how easily they have to oxidize.
Some metals oxidize easily, such as zinc and iron. Others like copper and silver take much longer to oxidize. The more difficult a metal is to react with, for example, oxygen in the air, the more noble that metal is. It's a thing of the nobility, of not wanting to mix with other commoners… Gold is one of the most popular metals. nobles, at the very end of the line, so much so that, under normal conditions, it doesn't react with oxygen and so it doesn't oxidizes. Therefore, we find gold in nature as a metal, without being linked to other elements.
