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.
An anion carries a negative charge and has more electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter to the calculation. The number of protons of an atom cannot change, so you add or subtract electrons to get the correct charge.
