Identify an actinoid element from following.
- A No
- B Mo
- C Co
- D Ce
Answer & Solution
Correct Answer
(A) No
Step-by-step Solution
Detailed explanation
Here's why:
- The actinoid elements (or actinides) are the elements in the periodic table that are found in the actinide series, which are the 15 elements from atomic number 89 to 103. These elements are all located in the f-block and are typically radioactive.
- Cerium (Ce) is an actinoid element, as it has the atomic number 58 and is part of the lanthanide series, which is sometimes mistakenly conflated with the actinide series. However, it is considered part of the f-block elements, but not an actinide specifically.
