The difference between $ferrous$ $"ferrous"$ and $ferric ions$ $"ferric ions"$ , and the parent iron metal?

Clearly ALL three species are in different formal oxidation states, which we conceive on the basis of electron transfer:

$Fe rarr underbrace(Fe^(2+))_"ferrous ion" + 2e^(-)$

$Fe rarr underbrace(Fe^(3+))_"ferric ion" + 3e^(-)$

We don't know their physical states. They may be ions in solution, or salts.... $"ferrous chloride"$ is $FeCl_2$ ; $"ferric chloride"$ is $FeCl_3$ .

What is the oxidation state of iron metal?
