To determine stability, you need to calculate the neutron to proton ratio. If you were to plot these on a graph (neutrons on the y-axis and protons on the x-axis), you would get a band of stability for elements 1-82. All non-radioactive elements are within this band. Radioactive elements are found outside the band (page 811, figure 25-11).
