How many neutrons are in thallium
WebSince lead lead 's atomic number is 82 82, Pb Pb has 82 82 protons. 82 82 protons. Fill in the known values where N N represents the number of neutrons. 207 = 82+ N 207 = 82 + N. Rewrite the equation as 82+N = 207 82 + N = 207. 82+N = 207 82 + N = 207. Move all terms not containing N N to the right side of the equation.
