Differentiate between metals and non-metals on the basis of their physical properties (four points).
Difference in Physical Properties of Metals and 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.|
