The metallic bond strength in first transition series increases from:
  • A
    $$Sc$$ to $$Mn$$
  • B
    $$Sc$$ to $$Cr$$
  • C
    $$Cr$$ to $$Zn$$
  • D
    $$Sc$$ to $$Cu$$

Solution

The increase in the no. of unpaired electrons increases the strength of the metallic bond in transition elements.
$$\Rightarrow \ Sc$$ to $$Mn$$
