Limits of nuclear existence: drip lines and superheavies
Only some combinations of protons and neutrons form nuclei that hold together: add too many neutrons and the extras fall off, add too many nucleons overall and the nucleus splits apart. Where these edges lie is known only for the lightest elements and is uncertain for the heaviest.
Why it matters
The edges of the nuclear chart test nuclear theory at its extremes and determine which nuclei can take part in element formation in stars.
