Less stable isotope from the list has to be predicted. Concept Introduction: Nuclear stability means that the nucleus is stable meaning that it does not spontaneously emit any kind of radioactivity. Nuclear stability can be explained based on neutron proton ratio (n/p) in the nucleus. For a stable atoms having low atomic number , n/p ratio is close to 1. When atomic number increases n/p becomes greater than 1. General rules for predicting the nuclear stability is given below, If the nucleus contains 2, 8,20,50,82 or 126 protons or neutrons, then they are generally considered as stable than the nuclei that do not possess these numbers. If the nuclei has even number of both protons and neutrons, then they are considered as stable as those with odd number of these particles. All isotopes of elements with atomic number higher than 83 are radioactive.

Students have asked these similar questions

1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on the LC-MS printout. How much different are they? 2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit, explain what each of these is and why they are present. 3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by calculating the accurate monoisotopic mass. 4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source. 5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number). For one point of extra credit, see if you can identify this molecule as well and confirm by…
