Question

Explain the physical prporties of metals with sutable examples

Answer 1

Answer:

.

Explanation:

the physical properties of metals are as follows

Ductile- the property of metals that they can be drawn into thin wire is known as a sonority metals are ductile is non metals are non-ductile. Gold is the most ductile metal other examples are silver aluminum copper etc

Malleability- the property of metals that they can be beaten into thin sheets is called malleability.Gold is most malleable.Non metals are not malleable.

six-Fold silver etc.

Lustrous-Metal have a shinny appearance which is called lustrous.Non metals are not lustrous. expection-graphite

Sonorus-Metals sounds a ringing sound which is called sonority. non metals are non-sonorus.ex-gold etc.

High conductivity of Electricity-Metals are good conductors of electricity where non metals are not good conductor of electricity. ex silver is the best conductor of electricity.

High thermal conductivity- Metals are good conductors of heat whereas non metals are not good conductors of heat.

ex-Copper,silver etc.

Brittleness-The property of non metals that break easily with hammer is called Brittle non metals are brittle whereas metals are non brittle.

Answer 2

Answer:

Metal have different kind of properties :

Explanation:

Metal are very hard and solid.

Metallic lustre :Metal have a property from which there surface appear shining that is called metallic lustre. For ex. Gold and Silver is most lustrous metal so they are used to make jewellery.

Malleability: Metal can be beaten and convert into a thin sheet this property is called malleability. For ex. Gold and Silver etc.

Ductility: Metal can be converted into a thin wire , this property is called ductility. For ex. A wire of about 2km can be drawn from one gram of gold.

Sonorous: The metal that produce a sound on striking a hard surface are said to be sonorous. School bell that produce sound is made up of brass or bronze copper ,zinc and tin.

Conduction of electricity and heat: Metal are good conductor of heat and electricity. For ex. Copper and silver.

Melting point : High.

Metal have some exception such as :

Mercury is liquid at room temperature.

Gallium and caesium have very low melting point.

Sodium ,lithium and potassium are so soft and can cut with knife.
