Question

difference between electrical conductivity of metals and non metals.

Answer 1

metals has the capability to conduct electricity because of their free electrons but the non metals do not conduct because they do not have any free electrons actually they have free electrons but they are non movable but electrons of metals are movable and or when they are found in solid state that's why they conduct electricity

also non metals are good conductors of electricity as we all know and metals are good conductors of electricity as we have studied before

Answer 2

metals has the capability to conduct electricity

metals are good conductors of heat and elctricity

where as non metal doesn't have the capability to conduct electricity

non metals are poor conductors of heat and electricity...

hope this will help you out
