Yes, oxygen is more reactive than copper. Oxygen can readily react with many materials, including metals like copper, to form oxides. This is why copper often forms a tarnished or oxidized surface when exposed to air.
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
Hydrogen peroxide reacts with the iron oxide (rust) on the surface of the metal, breaking it down into its chemical components. This reaction forms a hydrated iron oxide, which is typically orange in color.
Magnesium is a highly reactive metal that easily loses electrons to form compounds, whereas argon is an inert gas that does not readily react with other elements. Because of this stark difference in reactivity, it is unlikely for magnesium and argon to form a stable compound when combined.
CaO is a metal oxide. It is composed of calcium, which is a metal, and oxygen, which is a non-metal.
Metal rust will not harm trees. There are a number of fungus rusts that can harm plants but they are not metal rusts.
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.
The rust is an oxide of the base metal.

Yes it does!
They're metal and metal rusts because the iron in metal oxidizes.

Iron rusts.
Yes, metal is still a metal after it rusts. Rust is a form of corrosion that occurs on iron and its alloys, so the presence of rust does not change the fundamental properties of the metal. It is still classified as a metal even with the formation of rust.
This metal is iron.
