The main reason for larger number of oxidation states exhibited by the actinoids than the corresponding lanthanoids is:
Held on 30 Apr 2005 · Verified 9 Jul 2026.
more energy difference between 5f and 6d orbitals than between 4f and 5 d orbitals
lesser energy difference between 5f and 6 d orbitals than between 4f and 5 d orbitals
larger atomic size of actinoids than the lanthanoids
greater reactive nature of the actinoids than the lanthanoids
