Identify the incorrect statement among the following:

A

Shielding power of 4f electrons is quite weak

B

There is a decrease in the radii of the atoms or ions as one proceeds from La to Lu

C

Lanthanoid contraction is the accumulation of successive shrinkages

D

As a result of lanthanoid contraction, the properties of4d series of the transiton elements have no similarities with the 5d seriesof the elements.

Text Solution

Verified by Experts

As a result of lanthanoid contraction, the properties of the 4d series become similar to those of 5d series. Hence, option (d) is incorrect.
