Question

Write any three differences between metals and non-metals on the basis of

chemical properties?​

Answer 1

Answer:

Metals                                     Non-metals  

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

Metals reacts with oxygen to form basic oxides.

O

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

C+O

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

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.
