Differentiate between metals and non-metals on the basis of their physical properties (four points).

2

Difference in Physical Properties of Metals and Non-Metals:

Metals Non-metals
1. Metals are malleable and ductile. 1. Non-metals are neither malleable nor ductile.
2. Metals are good conductors of heat and electricity. 2. Non-metals are poor conductors of heat and electricity.(except graphite which is a good conductors of electricity).
3. Metals are lustrous. 3. Non-metals are non-lustrous.
4. Metals are strong .They have high tensile strength.(except sodium and potassium which are not strong and have low tensile strength). 4. Non-metals are not strong.They have low tensile strength.
