During bond formation, d-orbitals splits into _ of orbitals?
Correct answer: D. 2 sets
- A. 3 sets
- B. 4 sets
- C. 5 sets
- D. 2 sets
Explanation
When d-orbitals are involved in bonding, they split into two sets of energy levels, one set has higher energy than the other. This also results in the color development of transition elements in their compounds. This process is called d-d transition.

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.
