The point of dissimilarity between lanthanides and actinides is
- A three outermost shells are partially filled
- B they show oxidation state of \(+3\) (common)
- C they are called inner transition elements
- D they are radioactive in nature
Answer & Solution
Correct Answer
(D) they are radioactive in nature
Step-by-step Solution
Detailed explanation
Lanthanides and actinides both are not radioactive. Except promethium, all lanthanides are non-radioactive. While all actinides are radioactive.
