Oxidation state in Actinoids
- In general the oxidation state of these elements is +3 (similar to lanthanides).
- They also exhibit +4 oxidation states.
- Some of the elements also exhibit higher oxidation states.
- The oxidation state initially rises to the middle of the series (+4 for Th to +5, +6 and +7 for Pa, V and Np) and then descends in the succeeding elements.
