Answer # 19: iron- 56



Question # 20: Which experiment was used to discover the nucleus of the atom?



Answer # 20: The gold foil experiment.



Question # 21: Calculate the atomic mass of the element with the following isotopes


Isotope Mass (amu) Percent abundance (%)

X-69 68.9257 60.12

X-71 70.9249 39.88
