Why is graphite a good conductor of electricity but diamond is not good conductor of electricity |
|
Answer» Diamond: each carbon atom has a covalent bond with four other carbon ATOMS in a tetrahedral ARRANGEMENT to form a rigid structure. This is a stable arrangement where the outer electron layer of all atoms are filled with 8 electrons; so, there are no free electrons to move and CREATE electric current. Thus diamond is an insulator/dielectric. |
