Editing Neutron (section)

=== Electric charge ===
The total electric charge of the neutron is {{val|0|u=[[elementary charge|''e'']]}}. This zero value has been tested experimentally, and the present experimental limit for the charge of the neutron is {{val|-2|(8)|e=-22|u=[[elementary charge|''e'']]}},<ref name="PDGLIVE">
