Question

The main reason for larger number of oxidation states exhibited by the actinides than the corresponding lanthanides, is (A) lesser energy difference between 5f and 6d orbitals than between 4f and 5d orbitals (B) larger atomic size of actinides than the lanthanides (C) more energy difference between 5f and 6d orbitals than between 4f and 5d orbitals (D) greater reactive nature of the actinides than the lanthanides

The main reason for larger number of oxidation states exhibited by actinides than corresponding lanthanides is lesser energy difference between 5f and 6d orbitals than between 4f and 5d -orbitals.

Q. The main reason for larger number of oxidation states exhibited by the actinides than the corresponding lanthanides, is

lesser energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

larger atomic size of actinides than the lanthanides

more energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

greater reactive nature of the actinides than the lanthanides

The main reason for larger number of oxidation states exhibited by actinides than corresponding lanthanides is lesser energy difference between $5 f$ and $6 d$ orbitals than between $4 f$ and $5 d$ -orbitals.
