उत्तर
The transition metals ions having completely filled d-orbitals are colourless and diamagnetic.
Explanation:
Ions with completely filled d‑orbitals (e.g., d10 species) cannot undergo d-d electronic transitions, so they do not absorb visible light and are colourless. Also, because all d‑electrons are paired, these ions have no net spin and therefore show diamagnetic behaviour.
