Question

Actinoids show variable oxidation states

Answer 1

Frst of all ye 1 large oxidation state hai.

Actinides ths show a variety from +3 to +6.

Due to the very small energy gap between 5f, 6d and 7s sub shells.

Principal oxidation states are +3 and +4 and +3 oxidation state is the most stable.

The +4 oxidation state is the most stable.

Answer 2

Actinoides 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 distributions of oxidation states in actinoides are uneven.
