Examine the "region of stability" for the elements up to atomic number 20 by increasing the number of protons one by one and filling in the chart for the stable isotopes that exist by adjusting the number of neutrons. For these elements, about how many neutrons are there for each proton in their stable nuclei?

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)?
