Which is the most stable oxidation state of actinoids?(a) +2(b) +3(c)

1.	Which is the most stable oxidation state of actinoids?(a) +2(b) +3(c) +4(d) +5The question was posed to me by my school principal while I was bunking the class.I would like to ask this question from D and F-Block Elements in chapter D and F-Block Elements of Chemistry – Class 12
Answer» Correct option is (b) +3 To explain I would SAY: ACTINOIDS show variable oxidation states because of the smaller energy GAP between 5f, 6d and 7s orbitals. THOUGH 3+ is the most stable oxidation state, other oxidation states are possible because of the good shielding of f-electrons.
