Neutrons have zero charge.
In other words they have no charge.

Neutrons are made up of two down quarks and an up quark .
Down quarks contain a fractional electric charge of -1/3 .
Up quarks contain a fractional electric charge of +2/3 .
Neutron
= Down Quark + Down Quark + Up Quark
= -1/3 + (-1/3) + 2/3
= -1/3 -1/3 + 2/3
= -2/3 + 2/3
= 0/3
Therefore the neutron has a charge of 0 . In other words, the neutron is neutral.
