Recall that the neutron is a subatomic particle found in the nucleus of an atom alongside protons.
Understand that electric charge is measured in units of the elementary charge, denoted as +1 or -1 for protons and electrons respectively.
Recognize that the neutron is electrically neutral, meaning it has no net electric charge.
Therefore, the magnitude of the electric charge of a neutron is zero, which means it neither has a positive nor a negative elementary charge.
This neutrality is why the neutron is represented as having 0 elementary charges in simplified models.
