How many neutrons are in Pb-210?

Answer 1

The "210" is the mass number. The mass number is the sum of the number of neutrons and the number of protons. So if you can locate a Periodic Table, you can see that lead's atomic number of 82, which means it has 82 protons. If you do a little subtraction (210-82), you can find the number of neutrons in this particular isotope, which is 128.

Answer 3

When 210Pb decays by beta emission, the daughter nuclide is 210Bi.

Answer 4

Lead, with an atomic number of 82, would have 126 neutrons if the isotope in question had a mass number of 208.

Answer 5

Polonium-210 is a derived from bismuth-210 with 127 neutrons.

Answer 6

127 neutrons.
