Which of the following statements is false about transition metals?
Correct answer: C. All transition metal compounds are paramagnetic
- A. They form complexes
- B. They show variable valency
- C. All transition metal compounds are paramagnetic
- D. They form coloured ions
Explanation
Transition metals commonly form complexes, show variable oxidation states, and produce coloured ions because their d orbitals can participate in bonding and electronic transitions. The statement that all their compounds are paramagnetic is false because species with completely filled d subshells, such as Zn2+, have no unpaired electrons and are diamagnetic.

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.
