Oxygen on metals may have many different effects depending on the metal and what the oxygen is combined with. Oxygen combined with moisture on the metal of steel or iron will cause the metal to rust.
Alkali earth metals react with oxygen to form basic oxides.
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.
The pattern of reactions of metals with oxygen is based on their position in the reactivity series. Highly reactive metals like potassium, sodium, and calcium react vigorously with oxygen to form metal oxides. Less reactive metals like iron and copper react slowly with oxygen, forming metal oxides or hydroxides. Noble metals like gold and platinum do not react with oxygen at all under normal conditions.
Metals tend to lose electrons when they combine with non-metals like oxygen, forming positive ions. These positive ions then combine with the negative ions of non-metals like oxygen to form compounds, such as metal oxides.
Water and oxygen can be used to compare the reactivity of metals. More reactive metals will react with water to form metal hydroxides and hydrogen gas, and with oxygen to form metal oxides. Less reactive metals may not react with water or oxygen at all.

how do metals react with oxygen
Alkali earth metals react with oxygen to form basic oxides.
Au and Pt are some metals which do not react with O.
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.

Au or Pt are highly stable and they are noble metals as they do not react with oxygen readily
Several gasses can react with metals, but due to the fact that you are asking for a single gas, the most likely answer that you will be looking for is Oxygen. Oxygen reacts with many metals (and non-metals).
