Chemistry - f-block Question with Solution | TestHub
The general valence shell electronic configuration of f-block elements is:
[noble gas] , where in the case of lanthanides and in the case of actinides.
What are the consequences of lanthanide Contraction?
Options:
Answer:
Solution:
Question Explanation:
Find the consequences of lanthanide contraction.
Concept:
This question is based on lanthanide contraction.
Solution:
Lanthanide contraction is the progressive decrease in atomic and ionic radii of the lanthanide elements.
This phenomenon has several consequences.
(A) Radii of are almost the same. This is a consequence of lanthanide contraction.
(B) Lanthanides exhibit similar chemical properties due to the same valence shell configuration and similar size. This is a consequence of lanthanide contraction.
(C) Basic character of hydroxides of lanthanides gradually decreases across the series. This is a consequence of lanthanide contraction.
(D) All of these.
Final Answer:
The correct option is (D)
