How many electrons protons and neutrons are in lead?

Answer 1

Lead, atom number 82, has 4 natural occurring isotopes Pb-204, 206, 207 and 208.

They all have 82 protons and 82 electrons.

The neutron number varies from 122, 124, 125 and 126 respectively.

(Remember: atom number = p+ = e- and mass number = p+ + n0 )

Pb-207 has 82 protons, 82 electrons and 125 neutrons

Answer 2

The number of protons and electrons is same as its atomic number. To find neutrons, subtract the atomic number from atomic mass.

Answer 3

electrons - 82

protons - 82

and for the most common isotope of lead there are

neutrons - 125
