Question

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

Answer 1

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 and non metals are different in chemichal properties

metals have the the power to regains its form and also known as a physical change

non metals can not regain its original state and also known as chemical change.
