Question

Give any five difference between metals and nonmetals

Answer 1

Explanation:

metals

1) these are solids at room temperature except Mercury

2) these are very hard except sodium

3) these are malleable and ductile

4) these are shiny

5) electropositive in nature.

non metals

1) these exist in all 3 states.

2) these are soft except diamond

3) these are brittle and can break down into pieces

4) these are non- lustrous except iodine

5) electronegative in nature.

Answer 2

Answer:

1. On the basis of physical properties :

• Metals are malleable but nonmetals are non - malleable.
• Metals are Ductile but metals are non ductile .
• Metals are lustrous but non metals are brittle . (Except Diamond)
• Metals are sonorous but non metals are non - sonorous .
• Metals are good conductors of electricity but non metals are insulators .(Except Graphite)

2. On the basis of chemical properties :

• Metals are electron's donor but non metals are electron's acceptor .
• Metals forms cations but non metals forms anions .
• Metals forms basic oxides but non metals forms acidic oxides .
• Metals generally contains 1,2or3 electrons in valence shell but non metals generally contains 5,6or7 electrons in their valence shell .
• Metals are electro positive but non metals are electronegative.
