Question

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

Answer 1

hyy mate ✌️

Metals Non-metals

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

Metals reacts with oxygen to form basic oxides.

4Na + O_2 \rightarrow 2Na_2O4Na+O

2

→2Na

2

O

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

C + O_2 \rightarrow CO_2C+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_2O \rightarrow 2NaOH + H_22Na+2H

2

O→2NaOH+H

2

Non-metals do not react with water.

Metals react with dilute acids to form salt and H_2H

2

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

Metals react as reducing agent by donating electrons.

Na \rightarrow Na^+ + e^-Na→Na

+

+e

−

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

Cl_2 + e^- \rightarrow Cl^-Cl

2

+e

−

→Cl

hope it will help you ❣️
