Fe3jonen
Fe3jonen, also known as ferric ion or iron(III) ion, is a chemical species with the formula Fe3+. It is a common oxidation state of iron, particularly in its compounds. The ferric ion is characterized by having three electrons removed from its neutral iron atom, resulting in a stable d5 electronic configuration. This configuration is achieved by the removal of one electron from the 4s orbital and two electrons from the 3d orbital.
Ferric ions are typically found in a high-spin configuration, where the unpaired electrons are not paired up
Ferric ions are commonly encountered in various chemical compounds, including ferric chloride (FeCl3), ferric sulfate (Fe2(SO4)3),
The ferric ion is often involved in redox reactions, where it can be reduced to the ferrous
