The ability of transition elements to form complexes is due to:
Correct answer: D. All of these
- A. Small size of metal ion
- B. Highly charged metal ion
- C. Availability of empty d orbitals
- D. All of these
Explanation
A. Small size of metal ion:Smaller metal ions have a higher charge density, which enhances their ability to attract and hold onto ligands, forming stable complexes.B. Highly charged metal ion:Higher charge on the metal ion increases the electrostatic attraction between the metal ion and the ligands, promoting the formation of complexes.C. Availability of empty d orbitals:Transition metals have empty or partially filled d orbitals that can accept electron pairs from ligands, allowing them to form coordinate covalent bonds and stabilize the complex.Thus, all these factors collectively contribute to the complex-forming ability of transition elements.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
