Why is graphite used for making dry cell electrodes but diamond is not?
Advertisements
उत्तर
Graphite is a good conductor of electricity. Therefore, it is used for making dry cell electrodes. Whereas, diamond does not conduct electricity, as it has no free electrons and all its valence electrons go into the formation of strong covalent bonds.
