Best Answer

Actinoids shows +3 oxidation state in general. There is a greater range of oxidation states varying from +3 to +7. This variation is due to the fact that 5f, 6d and 7s levels are of comparable energies. Due to uneven distribution of oxidation states among actinoid elements, their study becomes somewhat difficult.

e.g., maximum oxidation states = +4 in Th

+ 5 in Pa

+6 in U

+ 7 in Np
