Question:
Assertion (A): Actinoids show irregularities in their electronic configurations.
Reason (R): Actinoids are radioactive in nature.
Assertion (A): Actinoids show irregularities in their electronic configurations.
Reason (R): Actinoids are radioactive in nature.
Reason (R): Actinoids are radioactive in nature.
Show Hint
When studying actinoids, focus on their complex electronic configurations and their radioactive nature.

- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false, but Reason (R) is true.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Actinoids do indeed show irregularities in their electronic configurations, mainly due to the f-orbitals and their greater number of electrons. However, their radioactivity is not the cause of this irregularity. The reason is unrelated to their electronic configuration.
