In \(3 d\)-transition series, which one has the least melting point?
- A \(\mathrm{V}\)
- B \(\mathrm{Zn}\)
- C \(\mathrm{Mn}\)
- D \(\mathrm{Cu}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Zn}\)
Step-by-step Solution
Detailed explanation
The melting points of \(3d\)-transition elements depend on the strength of metallic bonding, which is determined by the number of unpaired electrons available for delocalization. In the \(3d\) series, the electronic configuration of Zinc is \([Ar] 3d^{10} 4s^{2}\). Since all…
