Transition metals are not characterized by : — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Step 1: Review the characteristic properties of transition (d-block) metals. Step 2: Transition elements generally form colored ions/compounds due to d-d transitions, possess high melting and boiling points due to strong metallic bonding, and have a high tendency to form complex compounds due to small size and available vacant d-orbitals. Step 3: Because d-block elements have both ns and (n-1)d electrons available for chemical bonding, they typically display variable oxidation states (variable valency) rather than a fixed valency.
