Conductivity
Metals are usually elements that are the conductors of electricity and heat. Non-Metals are poor heat and electricity conductors.
Non-Metals can be divided in to two groups: · Non-metals with low electrical conductivity · Non-metals with moderate electrical conductivity Some non-metals are semiconductors, which is a non-metal that’s electrical conductivity increases with the temperature. Electrical conductivity of metals decreases with increasing temperature, but the conductivity of semiconductors increases with increasing temperatures |
