उत्तर
The reason for greater range of oxidation states in actinoids is attributed to 5f, 6d and 7s levels having comparable energies.
Explanation:
Actinoids show a greater range of oxidation states because the energy difference between their 5f, 6d, and 7s orbitals is very small.
This means electrons from all these orbitals can take part in bonding, allowing multiple oxidation states like +3, +4, +5, +6, and even +7.
