Both protons and neutrons have a magnetic moment. Unless the nucleus contains an even number of protons and an even number of neutrons, the atomic nucleus has a net magnetic moment. A nucleus must have a net magnetization for it to be discernible using magnetic resonance spectroscopy. From the list below circle possible candidates for magnetic resonance spectroscopy (you may need to look at a periodic table, unless specified otherwise choose the most abundant isotope for each element ): Carbon¹³ ...

At low atomic numbers, stable atomic nuclei have roughly equal numbers of protons and neutrons (a ratio of 1:1). How does the neutron/proton ratio change for stable nuclei as the atomic number increases? What is the approximate n:p ratio for elements near the end of the Periodic Table (atomic numbers above 80)?
