Do a search for the isotopes of gold. The list should give you each of the isotopes with its "mass number" (there are about 35 isotopes beginning with Au-172 and going through Au-205. ) The mass number is the total number of protons + neutrons. Since gold is element #79 all of its isotopes have 79 protons so just subtract 79 from the mass numbers to get the neutrons. Assuming we are talking about neutral gold atoms, the electrons = protons = 79.

Although gold (Au) has multiple isotopes, only one of these isotopes is stable; as such, it is considered a monoisotopic element.
Standard atomic mass: 196.966569(4) u

This may help you a bit.
You could also try Wikipedia , search "Isotopes of gold""

Isotopes other than those of hydrogen do not have special names.
