Which of the following is a characteristic property of d-block elements?
- A.They form only ionic compounds
- B.They exhibit variable oxidation states
- C.They are all radioactive
- D.They have very low melting points
Show correct answer & step-by-step solution
Correct answer: B — They exhibit variable oxidation states
Solution
- Transition metals have valence electrons in both ns and (n-1)d orbitals.
- The energy gap between these orbitals is small.
- This allows electrons from both subshells to participate in bonding, leading to variable oxidation states.
- Hence the answer is (B).
