Question

How can you classify metals and non-metals based on the properties of malleability and ductility?
Give examples to support your answers​

Answer 1

• Malleability is the property by which a substance can be beaten into thin sheets. For eg., copper, aluminium and iron can be flattened on beating.
• Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire. Examples: Most metals like, including gold, silver, copper, erbium, terbium, and samarium.
• Non-metals are neither malleable nor ductile, they are brittle.

Answer 2

Answer:

Explanation:

Malleability-- Metals are malleable, i.e. they can be beaten into thin sheets. Non-metals are not malleable. Eg- iron is malleable but coal is not.

Conductivity-- Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity. (exception: graphite) . Eg- copper is a good conductor of  electricity but wood is not.

Ductility--  Metals are ductile, i.e. they can be drawn into thin wires. Non-metals are not ductile.  Eg- silver is ductile but wood is not.

Sonorous-- Metals are sonorous, i.e. they produce a typical metallic sound when hit with something. Non-metals are not sonorous.  Eg- zinc is sonorous but sulphur is not.

Lustrous-- Metals have metallic shine; called luster. Non-metals are usually dull. (exceptions: diamond and graphite) . Eg- iron is lustrous but wood is not.

Physical State-- Most of the non-metals are available as solid at room temperature; except mercury. Sodium and potassium are so soft that they can be cut with knife. Non-metals are available in all the three states of matter. Eg- Manganese is solid at room temperature but Nitrogen is in gaseous form.
