Oxygen is a non metal element. There are 8 electrons in a single atom.
I'M NOT A MECHANIC but if I'm reading this right it is a heated oxygen sensor , (bank 2 , sensor 1 ?) Which would be the heated oxygen sensor on the driver's side of the engine , either screwed into the exhaust manifold or into the exhaust pipe near the engine. (Helpfull)
Painting a material that rusts, usually an iron rich material like steel, keeps the metal from exposure to the environment such as air and humidity. Rust is actually the oxidation of metal, and protecting metal with paint does not allow this to happen.

In its elemental form, calcium is made of electrically neutral Ca atoms. It is s silvery, highly reactive metal, that vigorously reacts with water. The calcium in milk is in the form of Ca2+ ions, which are chemically stable.
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
Metals in the reactivity series from aluminium to copper react with oxygen in the air to form the metal oxide. Aluminium and Zinc reacts very quickly, Iron reacts slowly at room temperature. Tin, Lead and Copper reacts with Oxygen in air when heated. Silver, Gold and Platinum do not react with Oxygen in air

Magnesium is the metal which reacts with oxygen to form magnesium oxide.
Any metal that reacts with oxygen will produce a metal oxide. For example, magnesium reacts with oxygen to produce magnesium oxide, and zinc reacts with oxygen to produce zinc oxide. It is helpful to know the general word equation: metal + oxygen -> metal oxide
oxides are formed when a element reacts with Oxygen
al2o3
It reacts rapidly but not violently unless heated.
Iron and Zinc
For example uranium react with oxygen but not with water.
rust or tarnish
Brooks metal ;)
