In air, bare zinc will form a dense but thin layer of oxide on its surface which protects the metal below from further corrosion, in much the same way as Aluminium. The zinc oxide layer may also combine with carbon dioxide in the atmosphere to form a basic carbonate which may flake off, but a new oxide layer will form very quickly.
Zinc is the sacrificial element that sacrifices itself to protect steel from corrosion through a process called galvanization. Zinc forms a protective layer over the steel surface, preventing oxygen and moisture from reaching the steel and causing corrosion.
In galvanized steel, a thin coating of zinc is used to protect it from rust or corrosion.
Protect against rusting of the steel. The protection is achieved by preferential reaction of the zinc "sacrificing" itself by being oxidized, and therefore the protection does not last forever in an environment favorable to rusting.
Zinc has the chemical symbol Zn. It is a metallic element commonly used in batteries and as a coating to protect other metals from corrosion.
Zinc will corrode first when welded to copper, as zinc is more reactive than copper. This can lead to galvanic corrosion, where the zinc sacrificially corrodes to protect the copper.

Zinc doesn't rust; zinc protect iron (and alloys) from rusting.
no
Galvanising is the process of application of zinc coating on steel surfaces. It prevents steel surface from rusting.
Decay, in itself, is a process.However, decay is caused by decomposing bacteria, which are micro-organisms.

how do young protect itself
Copper-67 undergoes beta decay with a halflife of 59 hours, becoming stable Zinc-67.
how does 'what' protect itself.
The freon itself is odorless, although the oil in the system does have an odor.
