Explain the difference on the basis of properties(2) Physical properties of metals and non metal physical properties.

Answer»

Answer:

Explanation:

Metals Non-metals

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

Metals reacts with oxygen to form basic oxides.

4Na+O

→2Na

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

C+O

→CO

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

O→2NaOH+H

Non-metals do not react with water.

Metals react with dilute acids to form salt and H

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

Metals react as reducing agent by donating electrons.

Na→Na

−

Non-metals are oxidizing AGENTS that can GAIN the electrons.

−

→Cl
