Detailed Solution

It is highly challenging to examine actinoids. Because actinoids—especially the later members of the actinide family—are radioactive elements with extremely limited half lives.

The actinoids are radioactive substances with a brief half-life. The actinoid series elements could only be synthesized in nanogram quantities due to which it is very difficult to study.
