Question

List in tabular form any three chemical properties on the basis of which metals and nonmetals are they are differentiated

Answer 1

For metal

1 It reacts with oxygen to form its basic oxide

2 I react with water to form its hydroxide

3 they react with dil.acid to form its salt and hydrogen gas

Now non metal

1 it react with oxygen to form its acidic oxides

2 do not react with water

3 do not react with dil.acid

Answer 2

Diffrencebetween metal and non metal on the basis of there Chemical properties

1. METAL

a) lose electron easily to form cation.

b) form basic oxide . Some metal firm amphoteric oxide.

c) evolve hydrogen gas from water

NON METAL

a) gain electron easily to form anion.

b) form acidic oxide some non metals form neutral oxide also .

c) do not evolve hydrogen gas from water
