Why is graphite used as electrode
​

Answer 1

Answer:

Graphite is used in making electrodes because it is a good conductor of electricity due to the presence of free electrons. One valence electron of each carbon atom remains free and thus it is a good conductor of electricity.

Answer 2

Answer:

Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
