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

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.


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 mass number of lead that has 127 neutrons?

The mass number of an atom is the sum of its protons and neutrons. Lead (Pb) has an atomic number of 82, so it has 82 protons. If it has 127 neutrons, the mass number would be 82 (protons) + 127 (neutrons) = 209.


What is the number of neutrons in an atom of lead?

Pb (lead) 82 protons 82electrons 125 neutrons


What has 82 protons and 126 neutrons?

An atom with 82 protons and 126 neutrons corresponds to the element lead (Pb) in its most stable form, lead-208.


Does too many neutrons determine if an isotope is unstable?

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.


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 lead is made from?

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)
