Which of the following statements best describes a neutron's charge?
1. a neutron has a positive electrical charge.
2. a neutron has no electrical charge.
3. a neutron has a negative electrical charge.
4. it is unknown whether or not a neutron has an electrical charge.

a  proton  has positive charge of 1, that is, equal but opposite to the charge of an  electron. a  neutron, like the name implies, is neutral with no net charge.

the charge is believed to be from the charge of the  quarks  that make up the nucleons (protons and neutrons). a proton is made of two up quarks, with 2/3 positive charge each and one down quark with a negative 1/3 charge (2/3 + 2/3 + -1/3 = 1). a neutron is made up of two down quarks with a negative 1/3 charge each and one up quark with a positive 2/3 charge. (-1/3 + -1/3 + 2/3 = 0).
