Question

compare the physical properties of metal and non metal

Answer 1

⇔ Physical Properties of Non Metals :-

• Metals are malleable that is metals can be beaten into thin sheet with a hammer (without breaking).

• Metals are ductile that is metals can be drawn or streatched into thin wires.

• Metals are good conductor of heat.

• Metals are good conductor of electricity.

• Metals are lustrous and can be polished.

• Metals are solid at room temperature except mercury.

⇔ Physical Properties of Non Metals :-

• Non metals are either malleable nor ductile. Non metals are brittle.

• Non metals do not conduct heat and electricity.

• Non metals are not lustrous .

• Non metals are not strong. They are easily broken.

• Non metals have many different colours.

• Non metals are generally soft except diamond.

Answer 2

Metals:-

⇒ Physical state :- Metals are solid at room temperature except mercury and gallium

⇒ Melting & Boiling points :- Metals have high melting and boiling point except gallium and cesium

⇒ Density :- Generally have high density

⇒ Malleability & Ductility:- Metals are malleable and ductile

⇒ Electrical & Thermal conductor :- Good conductor of heat and electricity

⇒ Luster :- pososs shining luster

⇒ Sound :- Metals give sonorous sound

⇒ Hardness :- Generally hard except postassium ( K ) and sodium ( Na )

Non metals :-

⇒ Physical state :- Non metals generally exist as solid and gases except Bromine.

⇒ Melting & boiling point :- they have low melting and boiling point except diamond and graphite

⇒ Density:- Generally low density

⇒ Malleability and Ductility:- Neither Malleable nor Ductile

⇒ Electrical and thermal conductor :- poor conductor of heat and electricity except graphite.

⇒ Luster :- Do not have luster except Iodine

⇒ Sound :- Does not give sound

⇒ Hardness :- Gernerally Soft except Diamond.
