Most metals oxidize under the right conditions. Gold, platinum and palladium do not oxidize at room temperature, which is the reason they are used in jewelry and electronics. Stainless steel, titanium, tantalum and niobium are highly resistant to oxidation.

Rust is iron oxide. The forms Fe2O3, Fe3O4, and FeO are the most common. Rust is a porous coating, which allows air and water to get in contact with the base metal, and the rusting process continues. Iron and steel products except the many stainless steels will readily oxidize or rust in the presence of oxygen and water in the earth's environment. Stainless steels contain enough chromium (minimum of 13% Cr by weight) to retard the rusting process. The chromium contained in the alloy forms an oxide (oxidation!) that provides a thin barrier protecting the steel and making it "stainless." This does not mean it won't corrode eventually--only that it is highly resistant to oxidation.

Pure titanium is exceedingly resistant to attack from water and air. It can develop an extremely thin skin of oxidized titanium that provides a passive barrier separating the metal from its environment.

Anodization is a deliberate oxidization of aluminum (aluminum), titanium, magnesium, zinc or niobium that forms a passive barrier that protects the metal from further destruction.

Copper away from contact with other metals will oxidize to a strongly protective barrier coating, making the metal underneath durable. Copper alloyed with zinc (brass) and tin (bronze) also only oxidizes superficially, making these alloys stand up well to corrosion.

Why do metals oxidize?

Oxidizing is basically just rust. In a sense all metals oxidize at their element level. Aluminum however builds up a layer of aluminum oxide which prevents aluminum from further oxidizing.

What is the acid that will melt metal?

Acids don't actually melt metal, they oxidize or corrode them. Usually producing the corresponding metal salt and hydrogen gas. Most strong acids (hydrochloric, hydrobromic, hydroiodic, perchloric, nitric, and sulfuric acids) will oxidize metals in this manner. Some weak acids such as hydrofluoric acid can oxidize metals. Some metals, such as the alkali metals and alkaline earth metals will react with virtually any acid and even water. Nitric acid can oxidize copper, which normally doesn't react with acid. Aqua regia, a mixture of nitric acid and hydrochloric acid will oxidize gold and platinum, which are usually considered immune to corrosion.
