Why d-block element form complexes?
Why d-block element form complexes?
- A. due to larger size and higher nuclear charge
- B. due to small size and low nuclear charge
- C. due to small size and higher nuclear charge
- D. none of the above
Step-by-step solution
d-block elements (transition metals) have small atomic/ionic sizes and high nuclear charge (high effective nuclear charge), which enables them to attract ligands strongly and form coordinate bonds. Additionally, they have vacant d-orbitals to accept electron pairs, facilitating complex formation.
