MCQ
The correct order of atomic/ionic radii is
- ✓$Sc >T i > V > C r$
- B$Co > Ni > Cu > Zn$
- C$S^{2-}>Cl^->O^{2-}>N^{3-}$
- DNone of these
✓
Answer
Correct option: A.
$Sc >T i > V > C r$
a
$(a)\,\, (a)\, Sc > Ti > V > Cr$ (size decrease initially in $3d-$ series)
$(b) $ Correct order : $Zn > Cu > CO \approx Ni$
$(c)$ Correct order : $S^{2-} > Cl^{-} > N^{3-} > O^{2-}$
$(a)\,\, (a)\, Sc > Ti > V > Cr$ (size decrease initially in $3d-$ series)
$(b) $ Correct order : $Zn > Cu > CO \approx Ni$
$(c)$ Correct order : $S^{2-} > Cl^{-} > N^{3-} > O^{2-}$
