When light is exposed to transition element, then electrons jump from lower orbitals to higher orbitals in
Correct answer: B. Orbitals of d-subshell
- A. Orbitals of s-subshell
- B. Orbitals of d-subshell
- C. Orbitals of p-subshell
- D. Both A and B
Explanation
When d-orbitals are involved in bonding, they split into two energy levels (lower and higher). Electrons present in low energy level absorb a part of visible light and jump to higher energy level. This is called d-d transition. Due to this transition, metal ion show colour.

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.
