NEETChemistryd and f Block Elements
Why is the chemistry of elements succeeding the actinoids less known?
Options
- AThey are highly reactive
- BThey are unreactive
- CThey have unstable isotopes
- DThey are affected by the actinoid contraction
Correct answer
D. They are affected by the actinoid contraction
Step-by-step solution
Actinoid contractions, have extended effects on the sizes, and therefore, the properties of the elements succeeding them in their respective periods. Thus, the chemistry of elements succeeding the actinoids are much less known at the present time.
