What is one reason for the greater range of oxidation states in actinoids?

Options

  1. ASimilar atomic sizes
  2. BComparable energies of 5f, 6d, and 7s levels
  3. CHigher electron affinity
  4. DPoor shielding by 4f electrons

Correct answer

B. Comparable energies of 5f, 6d, and 7s levels

Step-by-step solution

The greater range of oxidation states in actinoids is in part attributed to the comparable energies of 5f, 6d, and 7s levels.
