Answer:
Property
Actinoides
Lanthanoides
(a) Electronic
configuration
The actinoides
invove the filling of
The lanthanoides
involve the gradual filling of
. 1
(b) Oxidation
states
Actinoides show
oxidation state such as +3 but they also show +2, +4,+5,+6 oxidation state,
i.e., Uranium.
Lanthanoides show
mainly +3 oxidation state except in few cases where it is +2 and +4. 1

(i)They do not form
complexes easily.
(ii) They do not
form oxacation .
(iii) Their
compounds are less basic.
(iv) They are non-
radioactive.
