Some properties are listed in the following table. Distinguish between metals and non-metals on the basis of these properties.
Properties
1. Appearance
2. Hardness
3. Malleability
4. Ductility
5. Heat Conduction
6. Conduction of Electricity

METALS

1) Metals are lustrous as they can shine.
2) Metals are hard.
3) Metals are malleable as they can be beaten into thin sheets without breaking.
4) Metals are ductile as they can be drawn into thin wires without breaking.
5) Metals can conduct heat as it has free electrons that can carry heat from one point to another.
6) Metals can conduct electricity as it has free electrons that can carry current from one point to another.

NON-METALS

1) Non-metals are non-lustrous as they cannot shine.
2) Non-metals are brittle.
3) Non-metals doesn't show malleability as they cannot be beaten into thin sheets.
4) Non-metals doesn't show ductility as they cannot be drawn into thin wires.
5) Non-metals cannot conduct heat as it has no free electrons that can carry heat from one point to another.
6) Non-metals cannot conduct electricity as it has no free electrons that can carry current from one point to another.
