Question

List the properties of exceptions properties and exceptions of nonmetals and metals

Answer 1

 Metals have a high melting point but CESIUM has a low melting point 
2) Metals are very hard but SODIUM and POTASSIUM are very soft 
3) Metals are a good conductor but LEAD is a poor conductor 
4) Metals have a high desity but LITHIUM has a lower density 
5) Metals are solid in room temperature but MERCURY is liquid    


) Metals are malleable: this means that metal can be beaten into a thin sheet with a hammer without breaking.
2) Metals are ductile: this means that metal can be drawn (stretched) into thin wires. All the metals are not equally ductile. Ex: copper and aluminium metal are very ductile.
3) Metals are good conductor of electricity and heat: this means that metal allows heat and electricity to pass through them easily. Ex: silver is the best conductor of heat.
4) Metals are lustrous (shiny) and can be polished.
5) ,Metals are generally hard: most of the metals are hard but all the metals are not equally hard. the hardness of metal varies from one to another. All the metals are hard except mercury.

Answer 2

Metals in pure form have a characteristic metallic lustre.

Metals are generally hard. However, hardness varies from metal to metal.

Metals are generally malleable. This means they can be beaten into thin sheets.

Metals are usually ductile. This means most metals can be drawn into thin wires.
