Identify the incorrect statement among the following:
A
Lanthanoid contraction is the accumulation of successive shrinkages.
B
As a result of lanthanoid contraction, the properties of 
series of the transition elements have no similarities with the 
series of elements.
series of the transition elements have no similarities with the series of elements.
C
Shielding power of 
electrons is quite weak.
electrons is quite weak.
D
There is a decrease in the radii of the atoms or ions as one proceeds from La to Lu.
Text Solution
Verified by ExpertsThe correct answer is:
B
In each vertical column of transition elements, the elements of second and third transition series resemble each other more closely than the elements of first and second transition series on account of lanthanide contraction. Hence the properties of elements of 
series of the transition elements resemble with the properties of the elements of 
series of the transition elements.
