Difference between Metal and Non metal on their physical properties:Metals:1. Metals are malleable. 2. Metals are ductile. 3. Metals are good conductors of heat and electricity. 4. Metals are Lustrous and can be polished. 5. Metals are solid at room temperature. 6. The melting and boiling points of metals are generally high. 7. All metals are strong. 8. Generally, metals are hard. 9. Metals are heavy. 10. Metals are sonorous. Non-Metals:1. Non-metals are non-malleable or brittle.2. Non-metals are non-ductile3. Non-metals are bad conductors of heat and electricity.4. Non-metals are non-lustrous and cannot be polished.5. Non-metals may be solid, liquid or Gases at room temperature.6. Non-metals have low melting and boiling points as compared to metals.7. Non-metals are not strong.8. Most of Non-metals are soft.9. Non-metals are light substances.10. Non-metals are non-sonorous.

For Metals-- malleable and ductile -- having shiny (gold and silver) and luster (shining ) type -- producing deep sharp rich loud ( e.g. bell formed of metal) -- hard For Non- Metals -- non-malleable and ductiless.-- not shiny as metal -- producing dull sound -- brittle

Physical Properties of Metals and Non-metals
Metal and non-metal are two broad categories of elements in the periodic table that exhibit distinct physical properties. Understanding these differences is essential in chemistry.

Appearance
- Metals: Metals are typically shiny in appearance.
- Non-metals: Non-metals can have various appearances, including dull, transparent, or colored.

Conductivity
- Metals: Metals are good conductors of heat and electricity.
- Non-metals: Non-metals are poor conductors of heat and electricity.

Density
- Metals: Metals are generally dense.
- Non-metals: Non-metals are less dense compared to metals.

Malleability and Ductility
- Metals: Metals are malleable and ductile, meaning they can be hammered into thin sheets or drawn into wires.
- Non-metals: Non-metals are brittle and cannot be easily shaped into thin sheets or wires.

Melting and Boiling Points
- Metals: Metals have high melting and boiling points.
- Non-metals: Non-metals have lower melting and boiling points compared to metals.

Hardness
- Metals: Metals are generally hard.
- Non-metals: Non-metals can be soft or hard, depending on the specific element.
In summary, metals and non-metals differ in their appearance, conductivity, density, malleability, ductility, melting and boiling points, and hardness. These physical properties play a crucial role in determining the behavior and uses of these elements in various chemical reactions and applications.
