CHXII08:THE D- & F-BLOCK ELEMENTS

321592 Reason of lanthanide contraction is:

1 decreasing nuclear effect
2 decreasing screening effect
3 negligible screening effect of f-orbitals
4 increasing nuclear charge

321593 Statement A :
Radii of the members of the third transition series is very similar to those of the corresponding members of the second series.
Statement B :
It is due to lanthanoid contraction.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.

321594 The atomic radius of \(\mathrm{\mathrm{Ag}}\) is closest to :

1 \(\mathrm{\mathrm{Ni}}\)
2 \(\mathrm{\mathrm{Hg}}\)
3 \(\mathrm{\mathrm{Au}}\)
4 \(\mathrm{\mathrm{Cu}}\)

321595 Although Zirconium belongs to \({\rm{4d}}\) transition series and Hafnium to \({\rm{5d}}\) transition series even then they show similar physical and chemical properties because

1 Both belong to d-block.
2 Both have same number of electrons.
3 Both have similar atomic radius.
4 Both belong to the same group of the periodic table.
