उत्तर
| S. No. | Physical properties | Metals | Non-metals |
| 1. | Malleability and ductility | They can be beaten into sheets and wires. | They cannot form sheets or wires. |
| 2. | Sonority | Metals are sonorous; they produce a ringing sound when beating. | They are non−sonorous. |
| 3. | Conduction | They conduct heat and electricity. | Non-metals do not allow heat and electricity to pass through them. |
| 4. | Chemical Properties | Metals generally react by losing electrons, forming basic oxides, and conducting electricity and heat. | Non-metals usually gain or share electrons, form acidic or neutral oxides, and are poor conductors of electricity and heat. |
| 5. | Nature of oxides | Metallic oxides are basic. | Oxides of non−metals are acidic. |
| 6. | Reaction with water | Metals react with water. | Non−metals do not react with water. |
| 7. | Reaction with acids | Metals react with acids to produce hydrogen gas. | They generally do not react with acids. |
