How do the magnetic properties of actinoids compare to lanthanoids?

Options

  1. AActinoids have higher magnetic susceptibility
  2. BActinoids have lower magnetic susceptibility
  3. CActinoids have similar magnetic properties
  4. DActinoids have no magnetic properties

Correct answer

B. Actinoids have lower magnetic susceptibility

Step-by-step solution

The magnetic properties of the actinoids are more complex than those of the lanthanoids. Although the variation in the magnetic susceptibility of the actinoids with the number of unpaired 5 f electrons is roughly parallel to the corresponding results for the lanthanoids, the latter have higher values.
