Lead or Pb ALWAYS has 82 protons.
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
Pb+4, Lead
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
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
Lead, (Pb) has an Atomic number of 82 (you can look this up on a periodic table).This means it has 82 Protons and a neutral atom also has 82 electrons.To find the number of Neutrons you subtract the Atomic Number (82) from the Atomic Mass (208).Therefore the number of Neutrons in this isotope of Lead is 208-82 = 126
Pb, Lead, has 82 protons.
Lead or Pb ALWAYS has 82 protons.
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
A lead (Pb) atom has 82 protons.

lead[Pb]
Any isotope of lead has 82 protons, it is (and stays) number 82 in the periodic table.
Pb+4, Lead
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
