Zn, Cd,Hg are not considered as transitions metals in true sense why? but still they are studied with transitions elements? how and why?

Expert Answer:

The electronic configurations of Zn, Cd and Hg are represented by the general formula (n-1)d10 ns2. The orbitals in these elements are completely filled in the ground state as well as in their common oxidation states. Therefore, they are not regarded as transition elements. But they are studied with transitions elements because they exhibit a number of characteristic properties, which are similar to the transition elements.
