It depends on the isotope (atoms of lead with different numbers of neutrons). There are three stable isotopes of lead:
- 206Pb has 124 neutrons
- 207Pb has 125 neutrons
- 208Pb has 126 neutrons

∙ 11y agoIn 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

∙ 7y agoThe 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 82 protons in its nucleus. Since the number of neutrons varies among different isotopes of lead, if we consider the most common isotope, which is lead-208, it has 126 neutrons.

What is the mass number of lead that has 127 neutrons?
209 since Lead is 82.
How many neutrons are in palladium -107?
61 neutrons.
How many protrons and neutrons does silicon have in the nucleus?
How many protrons and neutrons does silicon have in the nucleus?
What type of radiation is emitted when polonium-212 forms lead-208?
Polonium-212 loses 2 protons and 2 neutrons when it decays to lead-208. These 2 protons and 2 neutrons are lost as a single Helium nucleus. In other words, it is an alpha decay.
How many neutrons are in 28Al?
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
How many protons and electrons nd neutrons in lead?
Lead has: 82 Protons 82 Neutrons 125 Electrons
How many neutrons are in a normal number of led?
Lead has 125 Neutrons in each normal atom that is not an isotope.
What If there are 128 neutrons in Pb 210 how many neutrons are found in the nucleus of Pb 206?
Lead-210 has 82 protons, so 128 - 82 = 46 neutrons in Pb-210. Lead-206 has 82 protons, so since it's a different isotope, the number of neutrons will differ. Lead-206 has 206 - 82 = 124 neutrons.
Lead-210 and lead-206 are different of lead?
isotopes
What is Z A and N if the nuclide of lead that contains 1.5 times as many neutrons as protons?
For lead, the number of protons (Z) is 82, since the atomic number of lead is 82. If the nuclide contains 1.5 times as many neutrons as protons, then the number of neutrons (N) would be 1.5 times 82, equaling 123.
How many neutrons are in lead with a mass number of 210?
Number of neutrons = Mass number - atomic number = 210 - 82 = 128
What is the number of neutrons in an atom of lead?
Pb (lead) 82 protons 82electrons 125 neutrons
Does too many neutrons determine if an isotope is unstable?
Yes, having too many neutrons relative to protons can make an isotope unstable. Neutrons help bind together the nucleus, but if there are too many, the nucleus can become unstable and undergo radioactive decay to become more stable.
What is the mass number of an lead atom that has 80 neutrons?
The mass number of an atom is equal to the sum of the number of protons and neutrons in its nucleus. Since lead has an atomic number of 82 (number of protons), if the lead atom has 80 neutrons, then the mass number would be 82 (protons) + 80 (neutrons) = 162.
What is the mass number of lead that has 127 neutrons?
209 since Lead is 82.
What has 82 protons and 126 neutrons?
Lead-208, which is 52.3% of natural lead.
What element has 86 electrons 125 neutrons 82 protons?
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.
