Explain the physical properties of metals with suitable examples. (OR

1.	Explain the physical properties of metals with suitable examples. (OR) Explain briefly the physical properties of metals.
Answer» Physical properties of metals: 1. Lustrous: When we rub the surface of metals with sand paper they will shine. This property is called lustrous, e.g.: Iron, zinc etc. 2. Sonority: When we hit the metal surface they give a ringing sound is called sonority, e.g.: Iron, copper etc. 3. Malleability: Metals can be flattened into thin sheets. The property of flattening metals into thin sheets is called malleability, e.g.: Silver, Iron, copper. 4. Ductility: Metals can be drawn into wires. The property of drawing a metal to make fine wire is called ductility, e.g.: Silver, gold. 5. Electric conductivity: Electricity can be easily pass through metals. So they are called good conductors of electricity. e.g.: Silver, copper, iron. 6. Conductivity of heat: Metal absorbs heat quite easily. They are good conductors of heat, e.g.: Copper, iron.
