1.	The reason for greater range of oxidation states in actinoids is attributed to :(1) actinoid contraction(2) 5f, 6d and 7s levels having comparable energies(3) 4f and 5d levels being close in energies(4) the redioactive nature of actinoids
Answer» (2) Minimum or comparable energy gap between 5f, 6d and 7s subshell makes electron excitation easier, hence there is a greater range of oxidation states in actinoids.
