Question

write two difference in chemical and physical properties of metal and nonmetal

Answer 1

Your answer :

Metals :

● Metals are solid at room temperature.
Exception : Mercury is liquid at room temperature.

● Metals have lustrous surface.

● Metals are generally hard.
Exception : Sodium and potassium they are so soft that they can be cut with a knife.

● Metals are malleable. That is they can be hammered into thin sheets.
Example : Aluminium foil use for wrapping food items.

● Metals are ductile. That is they can be drawn into thin sheets.
Example : Silver and gold are highly ductile.

● Metals have high melting and boiling points.

● Metals are good conductors of heat and electricity.
Exception : Lead and Mercury are poor conductors of electricity.

● Metals are sonorous. That is they make a ringing sound when struck.

Non-Metals :

● Non-metals are either solid, liquid or gas at room temperature.

● Non-metals are non lustrous.

● They are generally soft.

● Non-metals are non-malleable.

● Non-metals are non-ductile.

● They are poor conductors of electricity.

● They have low melting and boiling points.

● Non-metals generally have low density.

● They are non-sonorous.

Hope this helps.

Have a nice day =)
