Question

Explain the difference between Metals and non-metals. 

Answer 1

S. No.	Physical properties	Metals	Non-metals
1.	Malleability and ductility	They can be beaten into sheets and wires.	They cannot form sheets or wires.
2.	Sonority	Metals are sonorous; they produce a ringing sound when beating.	They are non−sonorous.
3.	Conduction	They conduct heat and electricity.	Non-metals do not allow heat and electricity to pass through them.
4.	Chemical Properties	Metals generally react by losing electrons, forming basic oxides, and conducting electricity and heat.	Non-metals usually gain or share electrons, form acidic or neutral oxides, and are poor conductors of electricity and heat.
5.	Nature of oxides	Metallic oxides are basic.	Oxides of non−metals are acidic.
6.	Reaction with water	Metals react with water.	Non−metals do not react with water.
7.	Reaction with acids	Metals react with acids to produce hydrogen gas.	They generally do not react with acids.
