A primary goal of medievel alchemists was to turn base metals in gold. Typically they worked with lead as the starting metal, since it was heavy, cheap, and readily available. The nucleus of the most abundant isotope of gold has 118 neutrons and 79 protons. The most abundant isotope of lead has a nucleus with 126 neutrons and 82 protons. a) Write the formulas for these isotopes of gold and lead. Use the format: MassNumber_ElementalSymbol_AtomicNumber (e.g., for the isotope of mercury with 122 neutrons and 80 protons, you would write that as: 202_Hg_80) b) If you were a very advanced medieval alchemist and could remove individual protons and neutrons from the lead isotope described above to make the gold isotope, write the symbol for the isotope you removed from lead to turn it into gold.
