Question

Differentiate between metal and Non metal based on their chemical properties?​

Answer 1

Explanation:

Metals Non-metals

Metals are electro-positive. Non-metals are electronegative.

Metals reacts with oxygen to form basic oxides.

4Na+O

2

→2Na

2

O

Non-metals react with oxygen to form neutral or acidic oxide.

C+O

2

→CO

2

Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.

Metals react with water to form hydroxide and hydrogen.

2Na+2H

2

O→2NaOH+H

2

Non-metals do not react with water.

Metals react with dilute acids to form salt and H

2

. Non-metals do not react with dilute acid and they can not displace hydrogen.

Metals react as reducing agent by donating electrons.

Na→Na

+

+e

−

Non-metals are oxidizing agents that can gain the electrons.

Cl

+e

−

→Cl

Answer 2

$\large\frak{\underline{\underline{\red{Required \: answer:-}}}}$

Metals :-

Reaction with Oxygen

Metals react with Oxygen to form Metallic Oxides.

$\sf{Mg+O_2 \rightarrow MgO}$

Aqueous solutions of these oxides are Basic in  nature and turns red litmus to blue.

$\sf{MgO+H_2O \rightarrow Mg(OH)_2}$

Reaction with Water

Metals react with water to form metal Hydroxides.

Metals like Sodium, Potassium react vigorously  with water.

Metals like Iron, Copper react slowly with water.

Reaction with Acids

Metals react with acids to form metallic salts and  liberates Hydrogen gas which burns with a ‘pop’  sound.

Reaction with Bases

Metals react with bases to make complex salts and  produce Hydrogen gas.

Non-Metals :-

Reaction with Oxygen

Non-metals react with oxygen to form Nonmetallic oxides.

$\sf{S+O_2 \rightarrow SO_2}$

Aqueous solution of these oxides are Acidic in

nature and turns blue litmus to red.

$\sf{SO_2+H_2O \rightarrow H_2SO_3}$

Reaction with water

Non-metals generally do not react with water.

Reaction with acids

Non-metals generally do not react with acids.

Reaction with bases

Reaction of non-metals with bases are complex.
