Difference between Metals and Non-metals on the basis of their physical properties

Difference between Metals and Non-metals on the basis of their physical properties:

Metals	Non-metals
1. Metals are generally solid at room temperature. (Except Mercury)	1. Non-metals exist in all the three states i.e solid liquid and gas.
2. Metals are generally hard. (except sodium which can be cut using a knife)	2. Non-metals are generally soft. (except diamond which us the hardest substance on the earth)
3. Metals are Malleable; means can be converted into thin sheets using a hammer. (except sodium and potassium)	3. Non-metals are generally brittle. Will broke down into pieces when beaten by a hammer.
4. Metals are ductile, means they can be converted into thin wires.	4. Non-metals are non ductile.
5. Metals have shiny surface or they are lustrous.	5. They are non lustrous. (except iodine)
6. Metals can lose electrons so they are electropositive in nature.	6. Non-metals gain electrons so they are electronegative in nature.
7. Metals are good conductors of heat and electricity.	7. Non-metals are bed conductors of heat and electricity. (Except graphite)
8. Metals are sonorous. They produce a sound on striking with a hard surface.	8. They does not do so they are not sonorous.
9. Metals generally have high densities. (except alkali metals)	9. Non-metals generally have low densities.
