Some properties are listed in the following table. Distinguish between metals and non-metals on the basis of these properties.
| Properties | Metals | Non-metals |
| 1. Appearance | ||
| 2. Hardness | ||
| 3. Malleability | ||
| 4. Ductility | ||
| 5. Heat Conduction | ||
| 6. Conduction of Electricity |
| Properties | Metals | Non-metals |
| 1. Appearance | have metallic lustre | dull |
| 2. Hardness | hard | soft |
| 3. Malleability | malleable | non-malleable |
| 4. Ductility | ductile | non-ductile |
| 5. Heat Conduction | good conductors | bad conductors |
| 6. Conduction of Electricity | good conductors | bad conductors/insulators |
[Extra information: Some properties of metals are given below:
- The density of metals is usually high.
- Metals are malleable and ductile.
- Metals form an alloy with other metals or non-metals.
- Some metals react with air and corrode. For e.g. Iron.
- Metals are good conductors of heat and electricity. Lead is an exception.
- Generally, metals are in a solid-state at room temperature. Except for Mercury. Mercury is in a liquid state.
- Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.
- Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals.
- Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous.
- Metals produce metal oxide and hydrogen gas while reacting with water.]
