Question

Distinguish between metals and non-metals on the basis of their chemical properties.

Answer 1

Answer :

Chemical properties of metal:-

#Reaction with oxygen

Metals reacts with oxygen to form metal oxide.

#Reaction with water

When metal react with water it forms metal hydroxide or oxide.

#Reaction with dilute acid

Metals reacts with diluted acid to form metals salt and hydrogen gas.

#Reaction of metal with salt of other metal

When metal reacts with salt sol. of other less reactive metal it displaces it from salt sol. and separate it out.

#Reaction with hydrogen

Generally metals do not combines with hydrogen but fer more reactive metal like sodium , potassium , calcium and magnesium combines with hydrogen and forms metal hydride.

Chemical properties of non metals:-

#Reaction with oxygen

Non metals reacts with oxygen to form non metallic oxide.

#Reaction of non metal with water

There is no reaction b/w non metals and water.

#Reaction with dilute acide

There is non reaction b/w non metals and dilute acide.

#Reaction of non metal with other non metallic salt

During this reaction a more reactive non metal displaces less reactive non metal from its salt sol.

#Reaction of non metal with chlorine

Non metals reacts with chlorine to form non metallic chloride.

#Reaction with hydrogen

Non metal reacts with hydrogen to form non metallic hydrogen

Answer 2

Metals reacts with oxygen to form basic oxides. Non-metals react with oxygen to form neutral or acidic oxide. Metal oxides and hydroxides bonds have ionic bonds. ... Non-metals do not react with dilute acid and they can not displace hydrogen.
