Question

According to the definition, the element $\underset{–}{\left(Hg\right)}$ (mercury) belonging to the 6th period of d - block does not come under transition elements.

• A. True
• B. False

Answer 1

The correct option is A True

The electronic configurations of $Zn,Hg,Cd$ are represented by general $(n-1)d^{10}$ ${ns}^2$. The orbitals are completed filled in these elements in the ground state as well as in their common oxidation state.

$\therefore Hg$ (mercury) belonging to $6^{th}$ period of d-block doesn't come under transition elements.
