Metal used for making joints in jewellery is : — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Joining delicate metal pieces in jewelry requires a solder alloy that has a lower melting point than the metals being joined. Step 2: Cadmium (Cd) lowers the melting temperature and improves the flow characteristics of silver-based solder alloys. Step 3: Consequently, Cadmium (Cd) is the key metallic component used for making solder joints in jewelry, matching option (d).
