Find number of correct orders of atomic radii which can be explained on the basis of "lanthanide contraction" is/are
(i) B < Al > Ga (ii) V > Nb ≈ Ta (iii) Sb > As (iv) Sc > Y > La
(v) Cu < Ag ≈ Au (vi) Ba > Ca > Mg (vii) Si > P > S (viii) Fe ≈ Co ≈ Ni

Answer:
ii) V > Nb ≈Ta
As the 6th period element and 5th period element are having nearly same atomic size due to lanthanoid contraction (Improper screening by f-electons).
hope this will help you
