SUMMARY
The discussion centers on calculating the number of excess electrons on a lead sphere with a mass of 8.00 grams and a net charge of -3.20 x 10^-9 C. The solution reveals that the number of excess electrons is 2.00 x 10^10. Given that the atomic number of lead is 82 and its atomic mass is 207 g/mol, the number of lead atoms in the sphere is derived using Avogadro's number, leading to a precise calculation of excess electrons per lead atom.
