Yay! You found them!
To anyone as Monk doesn't know:
Why does Iron have many oxidation states?
e.g. Fe2+ Fe3+
Alright - here's an answer.
https://www.vaia.com/en-us/textbooks/chemistry/chemistry-atoms-first-3-edition/c...The variety of oxidation states in transition metals is mainly due to the involvement of electrons
from both the outermost s and inner d orbitals in bonding,
and the specific stability associated with losing different numbers of these electrons.
Stable Electron Configurations.An element achieves stability by reaching a lower energy configuration.
For transition metals, losing or gaining electrons to balance s and d orbitals can lead to multiple stable oxidation states.
For example, iron (Fe) can achieve stability in both the +2 and +3 oxidation states.
In the +2 state, iron loses two 4s electrons while in the +3 state,
it loses two 4s electrons and one 3d electron.
