2005 · Q99

NEETChemistryD and F Block ElementsMCQ+4 / −1
More number of oxidation states are exhibited by the actinoids than by the lanthanoids. The main reason for this is
  1. A
    more active nature of the actinoids
  2. B
    more energy difference between 5f and 6d orbitals than that between 4f and 5d orbitals
  3. C
    lesser energy difference between 5f and 6d orbitals than that between 4f and 5d orbitals
  4. D
    greater metallic character of the lanthanoids than that of the corresponding actinoids.
