Question

Differentiate between metals and non metals on basis of their physical and chemical properties?​

Answer 1

Answer:

2. Metals are good conductors of heat and electricity. 2. Non-metals are poor conductors of heat and electricity.(except graphite which is a good conductors of electricity).

3. Metals are lustrous. 3. Non-metals are non-lustrous

Answer 2

Explanation:

DIFFERENCE BETWEEN METALS AND NON-METALS.

(Physical Properties)

1) Metals are malleable and ductile.

1) Non- metals are brittle (break easily). They are neither malleable nor ductile.

2) Metals are good conductors of heat and electricity.

2) Non-metals are bad conductors of heat and electricity. Except for graphite which is a good conduction of electricity.

3) Metals are lustrous and can be polished.

3) Non-metals are non-lustrous (dull) and cannot be polished. Except for iodine.

4) Metals are solids at room temperature.Except for mercury which is a liquid metal.

4) Non-metals may be solid, liquid or gases at the room temperature.

5) Metals are strong and tough.

5) Non-metals are not strong or tough.

DIFFERENCES IN CHEMICAL PROPERTIES.

1) Metals form basic oxides.

1) Non-metals form acidic oxides or neutral oxides

2) Metals displace hydrogen from water (or steam).

2) Non-metals do not react with water (or steam)

3) Metals displace hydrogen from dilute acids.

3) Non-metals do not react with dilute acids.

4) Metals form ionic chlorides with chlorine.

4) Non-metals form covalent chlorides with chlorine.

5) Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydrides.

5) Non- metals react with hydrogen to form stable, covalent hydrides.
