The atomic number of an atom refers to the

• number of electrons in a charged atom

• number of protons in the nucleus

• number of neutrons in the nucleus

• net electrical charge of the atom

Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of

• diode
