उत्तर
Properties | Metals | Non-metals |
1. State | Metals are generally solids at room temperature. | Non-metals are gases, liquids, soft solids at room temperature. |
2. Lustrous | Metals have lustre i.e. shine. | Non-metals do not have lustre i.e. do not shine. |
3. Malleability | Metals are malleable i.e. can be beaten into sheets. | Non-metals are non-malleable i.e. cannot be beaten into sheets. |
4. Ductility | Metals are ductile i.e. can be drawn into wires. | Non-metals are non-ductile i.e. cannot be drawn into wires. |
5. Conductivity | Metals are good conductors of heat and electricity. | Non-metal are poor conductors of heat and electricity. |
6. Melting and Boiling point | Metals have high melting and boiling points. | Non-metals have low melting and boiling points. |
