Oxide
Well I did and experiment for 30 days with 7up and an iron nail and it did not rust.
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
This really depends on the concentration of impurities in water. More the impurities, faster it will rust the iron nail. To reduce rusting of any iron the best way is to paint the nail.
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
It depends on the quality of the nail. If it is painted it Amy take long to rust. In general it may take a month or so for the nail to rust.
Iron present in the nail oxidizes in oxygen to form the iron oxides
It either cleans the nail, or makes the nail have rust.

They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.

it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted

rust
When the iron in a nail combines with oxygen it forms iron oxide. We call this rust.
A nail made out of just iron will rust really fast if it is exposed to oxygen. Nails available now, are galvanized nail which has a coating of copper metal on the surface of iron nail. This slows down process of rusting. Exposing a iron nail to water and other acidic environment along with oxygen, can make a nail rust pretty fast.

It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
