The correct order of radii is/are : — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Step 1: Recall the key characteristics of transition elements (d-block metals). Step 2: Transition metals have high melting and boiling points, are highly catalytic, and show variable oxidation states due to the participation of both ns and (n-1)d electrons in bonding. The inert pair effect is characteristic of heavy p-block elements. Step 3: Conclude that statement (c) is correct.
