A conductor is a substance that has free electron states (like a metal), or electric charges within it (like saltwater). The importance of a conductor is that if a conductor is placed in an electric field, there are electrically charged particles within it that can move, and will. Thus, the substance conducts electric current.

A neutron is a particle that resides in the nucleus of an atom and has a mass slightly larger than an electron and no net electric charge. Neutrons are held in atoms by the nuclear forces. A neutron not part of an atomic nucleus will decay into a proton and an electron. The number of neutrons in an atom have a strong effect on the stability of the atomic nucleus. For example, a hydrogen (1 proton) with no neutrons is stable. With one neutron, the hydrogen (called "deuterium") is still stable but more reactive in nuclear reactions. With two neutrons ("tritium"), it is radioactive.Neutrons and conductors have nothing to do with each-other.
