The elements in which d or f orbitals are in the process of completion are
Correct answer: D. Transition elements
- A. outer transition elements
- B. inner transition elements
- C. typical transition elements
- D. Transition elements
Explanation
Transition elements are those elements that have partially filled d orbitals in their ground state or common oxidation states. Both the first transition series (3d elements) and the second transition series (4d elements) fall into this category. Therefore, option (d) is correct as it broadly encompasses elements with d orbitals in the process of completion.

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.
