Description	Deutsch: Auftragung von Isotopen nach Art des radioaktiven Zerfalls. Orange und blaue Nuklide sind instabil, schwarze Kästen dazwischen zeigen stabile Nuklide. Die durchgezogene Linie repräsentiert die theoretische Position der stabilen Nuklide bei der Protonen- und Neutronenanzahl identisch sind. Es zeigt sich, dass Elemente mit mehr als 20 Protonen mehr Neutronen benötigen um stabil zu sein. English: Graph of isotopes by type of nuclear decay. Orange and blue nuclides are unstable, with the black squares between these regions representing stable nuclides. The unbroken line passing below many of the nuclides represents the theoretical position on the graph of nuclides for which proton number is the same as neutron number. The graph shows that elements with more than 20 protons must have more neutrons than protons, in order to be stable.
