It contains the periodic table and all the unstable isotopes of every element. The island of stability would be somewhere in the top right corner, outside the chart.
When you look at the half-life data, it’s pretty clear that lead is the last fully stable element. Anything past that line (126 neutrons) is more or less unstable, but not necessarily useless. For example, uranium and thorium are pretty far away, but they can still have practical applications.
Between hydrogen and lead, stable isotopes are abundant, but after lead, finding anything you can reasonably do chemistry with gets a bit scarce. When you go past plutonium 244, you’ll find even less chemistry there.
