If you look on the Periodic Table, you will find that the atomic number for lead is 82. This means that there will always be 82 protons. Next, assuming that there are not ions, the number of elections is also 82. Finally, you can see that the mass number of Pb is 207. 207-82=125 so there are 125 neutrons if you are referring to the most common isotope.
