प्रश्न
Give four differences between metals and non-metals with reference to their:
- Melting point and boiling point
- The conductivity of heat and electricity
- Malleability
- Solubility
उत्तर
| Metals | Non-Metals | |
| Melting point and boiling point | Metals have both high melting points and boiling points. | Non-metals have both low melting and low boiling point. |
| Conductivity of heat and electricity | They are good conductors of heat and electricity. | Nofi-metals are bad conductors of heat and electricity |
| Malleability | Metals are usually malleable. | All non-metals are non-malleable. |
| Solubility | Metals are generally insoluble in water and other organic solvents. | They are both soluble and insoluble |
