JEE · NEET Previous Year Question
Identify the incorrect statement among the following:
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- ALanthanoid contraction is the accumulation of successive shrinkages.
- BAs a result of lanthanoid contraction, the properties of series of the transition elements have no similarities with the series of elements.
- CShielding power of electrons is quite weak.
- DThere is a decrease in the radii of the atoms or ions as one proceeds from La to Lu.
Correct answer: B
Solution
(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.More d- and f-Block Elements PYQs
