Question

$Zn$, $Cd$ and $Hg$ are not regarded as transition elements. The electronic configurations of $Zn$, $Cd$ and $Hg$ are represented by the general formula $(n - 1)d^{10}ns^2$.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

Transition metals are defined as the elements having incompletely filled d orbitals. Since Zn, Cd and Hg have completely filled d orbital, they are not regarded as transition elements.
