what is sonorous,ductility and malleabilty?
The property of metals by which they can be beaten into thin sheets is called malleability. This is a characteristic property of metals.

Metals produce ringing sounds, they are said to be sonorous. The materials other than metals are not sonorous.

After performing the above activities, we can say that some materials are hard,lustrous, malleable, ductile, sonorous and good conductors of heat and electricity. The materials which generally posses these properties are called metals. The examples of metals are iron, copper, aluminium, calcium,magnesium, etc. In contrast, materials like coal and sulphur are soft and dull in appearance. They break down into powdery mass on tapping with hammer.They are not sonorous and are poor conductors of heat and electricity. These materials are called non-metals. The examples of non-metals are sulphur,carbon, oxygen, phosphorus, etc.

Metals like sodium and potassium are soft and can be cut with a knife. Mercury is the only metal which is found in liquid state at room temperature. These are exception.

The property of metal by which it can be drawn into wires is called ductility.
