Because of iron’s electronic configuration, it can react and exist in a wide variety of oxidation states, the most common being +2 and +3.
In those configurations it acts like a metal in its most familiar oxidation states, +2 and +3.
For example.,
Ferrous Sulfate, FeSO4 (oxidation state +2), and
Ferric Chloride FeCl3 (oxidation state +3).

However, iron actually can exist in oxidation states from -2 to +6. This is because its 26 electrons are arranged in the configuration: [Ar]3d64s2 electrons.
