Zn, Cd, Hg belong to d-block elements even though they do not have partially filled d-orbitals. Give reason.
✓

Answer

1. Zn, Cd, Hg belong to d-block elements even though they do not have partially filled d-orbitals either in their elemental state or in their normal oxidation states.
2. However they are treated as transition elements, because their properties are an extension of the properties of the respective transition elements.
