This is simple oxidation of the metal:
Eg when Iron rusts (such as in nails)
Iron + Oxygen ---> Iron Oxide
Fe(s) + O2(g) -----> Fe2O3 (s)
The reaction is usually quite slow and will cause the metal to corrode
Most metals with Oxidise in air, however not all will rust. Aluminium for example is too reactive to corrode, a thin layer of Aluminium oxide forms at the surface that provents the metal below from rusting.
Gold on the other hand is inert and with not oxidise readily in air.
Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
No. Rusting is a process exclusive to metals, particularly iron.
Near the sea exposed metals have a greater exposure to salts, which accelerate the rusting process.
No, salt and acid do not act as catalysts in rusting metals. Catalysts are substances that can speed up chemical reactions without being consumed in the process. In the case of rusting, salt and acid can actually accelerate the rusting process by increasing the conductivity of the water or by providing more ions for the reaction to occur.
Anhydrous calcium chloride can be used in the rusting of metals experiment to create a desiccating environment. By absorbing any water vapor present in the air, it helps to accelerate the rusting process by increasing the rate of oxidation of the metal. This can lead to a quicker and more visible demonstration of the rusting process for educational purposes.

Salt can accelerate the rusting process of metals by increasing the conductivity of water, which helps the flow of electrons that leads to oxidation. The presence of salt also lowers the electrical resistance of water, making it easier for the metal to corrode. Essentially, salt acts as a catalyst for the corrosion of metals.
No, halogen elements like fluorine, chlorine, bromine, iodine, and astatine do not rust because they are nonmetals and do not undergo the rusting process that typically affects metals like iron. Halogens are highly reactive in other ways, but rusting specifically applies to the oxidation of metals.
When metals react with the oxygen in the air, it is called oxidation. This process forms metal oxides on the surface of the metal, which can lead to rusting or tarnishing.
Rusting is an irreversible process.
