TM switching between oxidation states

Postby Petrina Kan 2I » Sun Nov 24, 2019 11:52 pm

I know Dr. Lavelle said that transition metals have many oxidation states that make it good for electron transfer, and that since the energy difference between the energy states it not that large they can switch between oxidation states. This part confused me slightly. How and why would the oxidation states be switching? When would these switches occur?

Transition metals can have multiple oxidation states because of their many electrons in the d subshell. The transition metals have several electrons in this shell with similar energies, so different numbers of them can be oxidized, depending the circumstances, resulting in different oxidation states.

This is why a transition metal such as Fe can have an oxidation state of either +2 or +3.
