The lanthanide contraction is responsible for the fact that
A. `Zr` and `Y` have about the same radius
B. `Zr` and `N//b` have similar oxidation state
C. `Zr` and `Hf` have about the same radius
D. `Zr` and `Ce` ahave same oxidation state
A. `Zr` and `Y` have about the same radius
B. `Zr` and `N//b` have similar oxidation state
C. `Zr` and `Hf` have about the same radius
D. `Zr` and `Ce` ahave same oxidation state
Correct Answer – C
Due to poor shielding of `(n – 2) f`- electrons, the size of `Zr, and `Hf` remains the same.
