It depends on the isotope (atoms of lead with different numbers of neutrons). There are three stable isotopes of lead:
In nature there are a number of isotopes of lead:
Lead-204, 122 neutrons
Lead-206, 124 neutrons
Lead-207, 125 neutrons
Lead-208, 126 neutrons
Lead-210, 128 neutrons
The number of neutrons is the difference between the mass number of an isotope and the number of protons. And of course each isotope has another number of neutrons. The natural isotopes of lead are: 204, 205, 206, 207, 208 and 210.
Lead has 125 neutrons. It also has 82 electrons and 82 protons.
it has 125 neutrons.

61 neutrons.
How many protrons and neutrons does silicon have in the nucleus?
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
The isotope barium-140 has 84 neutrons.
Lead has: 82 Protons 82 Neutrons 125 Electrons
Lead has 125 Neutrons in each normal atom that is not an isotope.
82 electrons 82 protons 125 neutrons
An isotope with too many neutrons can be unstable for example Hydrogen-3 is unstable while hydrogen-1 and 2 are stable. But so can one with too few neutrons, for example lead-204 is unstable while lead-206, 207, and 208 are stable.

Number of neutrons = Mass number - atomic number = 210 - 82 = 128
209 since Lead is 82.
Lead-208, which is 52.3% of natural lead.
Lead is an atom consisting of 82 protons and 82 electrons. The number of neutrons depends on the isotope of lead. Pb-207 isotope has 125 neutrons (207 - 82 = 125)
