The transition element which doesn't show variable valency?
Correct answer: C. Zn
- A. Cu
- B. Sc
- C. Zn
- D. Cr
Explanation
The answer to the question should be option C because Zinc does not show the variable valency as elements of the d-block. After all, the d-orbital is full. Its outer electronic configuration is 3d^10 4s^2 So, they tend to lose only 2 electrons from its outermost shell. Hence, only show a valency of +2 and no variable valency.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
