Q. Which of the following are correctly matched?

1. Ductility- drawn into wire
2. Malleability- drawn into sheets
3. Good conductors -copper and mercury
4. Non-metals- solids or gases

Select the correct answer from the codes given below:
Answer: Only 1, 2, and 4
Notes: The ability of metals to be drawn into thin wires is called ductility. Gold is the most ductile metal. Metals are good conductors of heat and have high melting points. The best conductors of heat are silver and copper. Lead and mercury are comparatively poor conductors of heat. The non-metals are either solids or gases except bromine which is a liquid. The ability of metals to be drawn into sheets is called malleability.
