Which element has completely filled d subshell in both atomic and ionic form?
Correct answer: D. Zn
- A. Cr
- B. Fe
- C. V
- D. Zn
Explanation
Zinc has a complete subshell. The electronic configuration of zinc is[ Ar] 3d¹⁰ 4s² so all the orbitals are filled. It is stable and does not need any electrons.

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.
