why do actinoids show more variable oxidation state as compared to lanthanoids?
Asked by vartika | 07 Nov, 2013, 09:52: PM
Expert Answer
- Actinides show a variety of oxidation states from +3 to +6.
- This is due to the very small energy gap between 5f, 6d and 7s sub shells.
- The principal oxidation states are +3 and +4 and +3 oxidation state is the most stable.
- The +4 oxidation state is the most stable in Th and Pu.
- +5 in Pa and Np and +6 is seen in U.
- The distributions of oxidation states in actinides are uneven.
