$Zn, Cd$

Vedclass · Answer

(A) Zinc $(Zn)$ and cadmium $(Cd)$ are relatively soft metals compared to other transition elements.They form weaker metallic bonds due to the presence of completely filled $d$-orbitals ($d^{10}$ configuration),which do not participate in metallic bonding.The melting point of $Zn$ is $419.5\,^{\circ}C$ and the melting point of $Cd$ is $321\,^{\circ}C$.Both of these values are below $500\,^{\circ}C$.

Which of the following have a melting point below $500\,^{\circ}C$?
