$Cr$ and $Cd$

Vedclass · Answer

(D) In the first transition series ($3d$ series),the element with the maximum melting point is $Cr$ due to the presence of a large number of unpaired electrons in the $d$-orbitals,which leads to strong metallic bonding.In the second transition series ($4d$ series),the element with the minimum melting point is $Cd$ because it has a completely filled $d^{10}$ configuration,resulting in weak metallic bonding.

The maximum and minimum melting points of the first and second transition series elements,respectively,are obtained with $-$
