Like all hadrons, neutrons are made of quarks. A neutron is made of two down quarks and one up quark. One up quark has a charge of +2/3, and the two down quarks each have a charge of -1/3. The fact that these charges cancel out is why neutrons have a neutral (0) charge. Quarks are held together by gluons.
Best Answer: The answer is C. Electron. The electrons of an atom, in the electron cloud, are the only subatomic particles that have a negative charge. The neutron, which is in the nucleus, has no charge, so it is neutral. The proton, which is also in the nucles, has a positive charge. I hope this helps you out. Source(s): Honors Chem.
