Can not be non metals be used as electrodes?
Electrodes should be a conductor of electric current, since, non-metals do not conduct electric current therefore, they cannot be used as electrodes.
Non-metals are generally non-conductors of electricity. The non-metal whose one of the forms can be used to make electrodes in electrolysis experiments is : (a) iodine (b) carbon (c) silicon (d) phosphorus
Non-metals are not good conductors of heat. Hence, they can also be called as:
Non-metals are not good conductors of heat hence they can also be called as conductors.
