Zinc amd mercury do not show variable valency like d-block elements be...
Explanation:
Zinc and mercury belong to the d-block elements, but they do not exhibit variable valency like other d-block elements. This is due to the following reasons:
1. Complete d-shells: Zinc and mercury have completely filled d-shells with 10 electrons. Hence, they do not exhibit any variable valency.
2. Absence of unpaired electrons: Another reason for the absence of variable valency is the absence of unpaired electrons in the d-orbitals. Zinc and mercury have only two electrons in their outermost shell, which occupy the s-orbital. Hence, they do not show any tendency to form multiple oxidation states like other d-block elements.
Conclusion:
In conclusion, the absence of variable valency in zinc and mercury is due to the complete filling of d-shells and the absence of unpaired electrons in the d-orbitals.

Zinc amd mercury do not show variable valency like d-block elements be...
Zn and Hg are pseudo transition elements and do not show variable valency as other d-block elements because their d orbital is completely filled in ground state as well as their common oxidation states.
