English: Periodic table with elements colored according to the half-life of their most stable isotope.
   Elements which contain at least one stable isotope.
   Radioactive elements: the most stable isotope is very long-lived, with half-life of over four million years.
   Radioactive elements: the most stable isotope has half-life between 800 and 34.000 years.
   Radioactive elements: the most stable isotope has half-life between one day and 103 years.
   Highly radioactive elements: the most stable isotope has half-life between several minutes and one day.
   Extremely radioactive elements: the most stable isotope has half-life less than several minutes. Very little is known about these elements due to their extreme instability and radioactivity.
