Question

Distinguish between mrtals and non metals on the basis of appearance mallaebility ductility hardness of electricity heat conduction

Answer 1

Metals : All the metals except Mercury are solids in the room temperature. they are shiny and lustrous. metals exhibit malleability, ductility. metals are hard materials they have high density. They do not conduct electricity in the solid state but conduct electricity in Aqueous solutions. They are good conductors of heat

Non metals: Generally non metals are liquids or gases at room temperature. They are dull. They are non malleable, non ductile ,they are soft do not conduct electricity and heat.
