How will you explain that the chemistry of the actinoid elements is not so smooth as that of the lanthanoids?

Options

  1. AActinoid elements have large number of oxidation states as the energy difference between 5f, 6d, and 7s orbita
  2. BActinoid elements have fewer oxidation states compared to lanthanoids.
  3. CActinoid elements have a more regular and predictable pattern of chemical behavior compared to lanthanoids.
  4. DActinoid elements have a higher density than lanthanoids, affecting their chemical properties.

Correct answer

A. Actinoid elements have large number of oxidation states as the energy difference between 5f, 6d, and 7s orbita

Step-by-step solution

Correct Option is : (A) Actinoid elements have large number of oxidation states as the energy difference between 5f, 6d, and 7s orbitals is very less but Lanthanoids show limited oxidation states.
