Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Step 1: Concept
Americium (Am) is a transuranic radioactive chemical element with atomic number 95.
Step 2: Meaning
Elements with atomic numbers 89 to 103 are classified as the actinide series.
Step 3: Analysis
Am (95) falls within the $5f$ block.
Step 4: Conclusion
Hence, correct answer is actinoids.
Final Answer: (E)
