Question

The chemistry of actinoids is more complicated as compare to lanthanoids. Give reason

Answer 1

because
1)actinoid elements shows variety oxidation state.
2)They are mostly radioactive and to study their properties is very difficult.
3)They are mostly present in small quantities
4)Their half life is extremely small.

Answer 2

Hey !!

This is because of the following reasons:-

(a) Actinoids are radioactive.

(b) Actinoids show wide range of oxidation states as energy between 5f , 6d and 7s subshells of the actinoids is small.

Good luck !!
