So 205 is the most common

Lead has: 82 Protons 82 Neutrons 125 Electrons
The most common isotope of Neon has 10 neutrons.
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.
Barium has 81 neutrons :D
The most common isotope of uranium is uranium-238 with 146 neutrons.
It depends on the isotope (atoms of lead with different numbers of neutrons). There are three stable isotopes of lead:206Pb has 124 neutrons207Pb has 125 neutrons208Pb has 126 neutrons
Lead has: 82 Protons 82 Neutrons 125 Electrons
146 neutrons.
In the most common isotope of silicon, there are 14 neutrons.
Lead has a total of 82 subatomic particles, which includes 82 protons and typically 126 neutrons in its most common isotope. Electrons can vary in number based on the charge of the ion.
Lead has 125 Neutrons in each normal atom that is not an isotope.
6 protons. The number of neutrons varies, but the most common isotope has 6 neutrons.
The most common isotope of Neon has 10 neutrons.
You take the atomic mass (the small number in the upper left corner of the square in the periodic table) and subtract the atomic number from it (the big bold number on the periodic table)
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.
Boron has 5 neutrons and 5 protons for its most common isotope
Sodium's most common isotope is sodium-23, which has 11 protons and 12 neutrons.
