Question
Because of lanthanoid contraction, which of the following pairs of elements have nearly same atomic radii ? (Nubmers in the parenthesis are atomic numbers).
Options
A.Zr (40) and Nb (41)
B.Zr (40) and Hf (72)
C.Zr (40) and Ta (73)
D.Ti (22) and Zr (40)
Solution
Due to lanthanoid contraction
atomic radii of Zr and Hf is almost similar.
atomic radii of Zr and Hf is almost similar.
