Question

The ions of metals of group-12 (Zn, Cd and Hg) have a complete d -shell, and so (A) behave like superconductors (B) are very high melting solids (C) do not behave like transition metals (D) behave like semiconductors.

Typical transition metals have partially filled d -orbital either in their elemental state or in most common oxidation state, but ions of metals of group-12 (Zn, Cd and Hg) have a completely filled d -subshell and so they do not behave like transition metals.

Q. The ions of metals of group- $12 (Z n, C d$ and $H g)$ have a complete $d$ -shell, and so

behave like superconductors

are very high melting solids

do not behave like transition metals

behave like semiconductors.
