State any five Physical Properties of Metals and Non-Metals.

Physical Properties of Metals:

1. Luster: Metals typically have a shiny appearance.
2. Malleability: Metals can be hammered into thin sheets without breaking.
3. Ductility: They can be drawn into wires.
4. Conductivity: Metals are good conductors of heat and electricity.
5. Density and Strength: Most metals have high density and are strong.

Physical Properties of Non-Metals:

1. Lack of Luster: Non-metals usually have a dull, non-shiny surface.
2. Brittleness: They are generally brittle and cannot be rolled into wires or sheets.
3. Poor Conductors: Non-metals are poor conductors of heat and electricity.
4. Lower Density: They often have lower density compared to metals.
5. Variability in States: Non-metals can be found in all three states – solid, liquid, and gas at room temperature.
