Where are the proton and nuetron located on the periodic table?

In modern periodic tables, they arent; in order to find the number of neutrons in an atom you must subtract the atomic number (the number of protons) from the atomic mass (rounded to the nearest whole number). In older ones (from the 1930s), neutrons are listed as Element 0, but outside of very extreme environments (specifically, the core of a neutron star), that element simply does not exist, so it's no longer on the table.
