It is formed when the Earth was being formed. As the Earth got bigger the iron seeped into the crust of the earth and kept going.
there are four allotrpic forms of iron...
Iron forms a cation.
Iron oxide (rust) forms as the iron is oxidized.
The word equation for the reaction when iron forms hematite in the Earth is: Iron + Oxygen → Hematite.
Iron, when it oxidizes.
Iron plus oxygen forms iron oxide, or plain old rust.

The ability to react with oxygen, which forms rust is a chemical property of iron.
The iron nail would rust the fastest, as its surface area is relatively larger compared to the other forms of iron listed. This allows more exposure to oxygen and moisture, which are essential for the rusting process to occur.
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
91.72% of all iron has 30 neutrons. But there are also stable forms of iron with 31 and 32 neutrons.
