Ions can be found both inside and outside the nerve cell. This is important for the transmission of nerve impulses. Additionally, ions can have either a positive or negative electrical charge, or no charge at all. Neutrons, on the other hand, are particles found in the nucleus of an atom and have no electrical charge. The electrical charge of a neuron is due to the movement of ions across its membrane, with the inside of the neuron having a negative charge relative to the outside.
