What kind of ionization was used to get this mass spectrum? 20.What element is represented here? You will have to look up isotopes of different elements to figure this out. 21.Do the peak intensities correlate with what we know about the natural abundances of each isotope? 22.Which isotope has the highest natural abundance, and what is the % abundance? 23.Which isotope has the lowest natural abundance, and what is the % abundance
