Transition elements form complexes because_?
Correct answer: C. Both A and B
- A. They have partially filled d orbitals
- B. They show variable oxidation states
- C. Both A and B
- D. They have strong bonding
Explanation
The correct answer is Both A and B. Transition elements form complexes due to their partially filled d orbitals, which can overlap with ligand orbitals, allowing the formation of coordinate bonds. Additionally, their variable oxidation states make it possible for these elements to participate in various redox reactions, enhancing their ability to form a wide range of complexes. Options A and B individually describe properties that contribute to complex formation, but both properties together provide the complete explanation. Option D is incorrect because while strong bonding is a feature of complexes, it does not specifically explain the ability of transition elements to form them.

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.
